The impurities observed in drug substances may arise during synthesis or may be derived from sources such as starting materials, intermediates, reagents, solvents, catalysts, and reaction by-products. During drug product development, impurities may be formed as a result of the inherent instability of drug substances, may be due to incompatibility with added excipients, or may appear as the result of interactions with packaging materials. The amount of various impurities found in drug substances will determine the ultimate safety of the final pharmaceutical product. Therefore, the identification, quantitation, qualification, and control of impurities are now a critical part of the drug development process. Various regulatory authorities focus on the control of impurities: the International Conference on Harmonization (ICH), the United States Food and Drug Administration (USFDA), the European Medicines Agency (EMA), the Canadian Drug and Health Agency, the Japanese Pharmaceutical and Medical Devices Agency (PMDA), and the Australian Department of Health and Ageing Therapeutic Goods. In addition, a number of official compendia, such as the British Pharmacopoeia (BP), the United States Pharmacopeia (USP), the Japanese Pharmacopoeia (JP), and the European Pharmacopoeia (EP) are incorporating limits that restrict the impurity levels present in APIs as well as in drug formulations. The Three Major Categories of Pharmaceutical Impurities According to ICH guidelines, impurities related to drug substances can be classified into three main categories: organic impurities, inorganic impurities, and residual solvents. 1. Organic impurities Organic impurities can arise in APIs or drug product formulations during the manufacturing process or during the storage of drug substances. They may be known, unknown, volatile, or non-volatile compounds with sources including starting materials, intermediates, unintended by-products, and degradation products. They may also arise from racemization, or contamination of one enantiomeric form with another. In all cases they can result in undesired biological activity. Recently, genotoxic pharmaceutical impurities, which may potentially increase cancer risks in patients, have received considerable attention from regulatory bodies and pharmaceutical manufacturers. In general, genotoxic impurities include DNA reactive substances that have the potential for direct DNA damage. Potential genotoxic impurities include process impurities or degradants, present at trace levels, which are generated during drug manufacturing and storage. As per FDA and EMA guidelines, potential genotoxic impurities are to be controlled at levels much lower than typical impurities. The recommended acceptable thresholds for genotoxic impurities in pharmaceuticals can be found in the guideline documents published by the USFDA and EMA (See the selected list of key publications provided at the end of this section). The ICH M7 guidance on genotoxic impurities is currently under 4 preparation with the working title "M7 Assessment and Control of DNA Reactive (Mutagenic) Impurities in Pharmaceuticals to Limit Potential Carcinogenic Risk". 2. Inorganic (elemental) impurities Inorganic impurities can arise from raw materials, synthetic additives, excipients, and production processes used when manufacturing drug products. Several potentially toxic elements may be naturally present in the ingredients and these elements must be measured in all drug products. A further group of ingredients may be added during production and must be monitored for elemental impurities once they are known to have been added. Sources of inorganic impurities include manufacturing process reagents such as ligands, catalysts (e.g., platinum group elements (PGE)), metals derived from other stages of production (e.g., process water and stainless steel reactor vessels), charcoal, and elements derived from other materials used in filtration. The United States Pharmacopeia (USP) is in the process of developing a new test for inorganic impurities in pharmaceutical products and their ingredients. The current Heavy Metals Limit Test (USP<231>) is widely acknowledged to be inadequate in terms of scope, accuracy, sensitivity, and specificity, and is due to be replaced with two new general chapters, Limits (USP<232>) and Procedures for Elemental Impurities (USP<233>), due to be implemented in 2013. In parallel with the development of USP<232> and USP<233>, the USP is also introducing a related method <2232> which is specific to dietary supplements. USP<232> defines new, lower permitted daily exposure (PDE) limits for a wider range of inorganic elemental impurities: As, Cd, Hg, Pb, V, Cr, Ni, Mo, Mn, Cu, Pt, Pd, Ru, Rh, Os, and Ir. A complete list of regulated elements and PDEs can be found in Agilent publication 5990-9365EN and the references therein. USP<233> further defines the sample preparation and method validation procedures that should be used for system suitability qualification of any instrumentation used for the analysis of elemental impurities in pharmaceutical materials. Validation of analytical instruments that are used for the new USP<232> and USP<233> methods will be performance based. USP<233> defines the analytical and validation procedures that laboratories must use to ensure that the analysis is specific, accurate, and precise. 3. Residual solvents Residual solvents are the volatile organic chemicals used during the manufacturing process or generated during drug production. A number of organic solvents used in synthesis of pharmaceutical products have toxic or environmentally hazardous properties, and their complete removal can be very difficult. In addition, the final purification step in most pharmaceutical drug substance processes involves a crystallization step which can lead to the entrapment of a finite amount of solvent which can act as a residual impurity or can cause potential degradation of the drug. Residual solvent levels are controlled by the ICH, USP, and EP. Depending on their potential risk to human health, residual solvents are categorized into three classes with their limits in pharmaceutical products set by ICH guidelines Q3C. The use of class I solvents, including benzene, carbon tetrachloride, 1,1-dichloroethane, 1,2-dichloroethylene, and 1,1,1– trichloroethane, 5 should be avoided. Class II solvents, such as methanol, pyridine, toluene, N,N-dimethylformamide, and acetonitrile have permitted daily exposure limits (PDEs). A few examples of common organic solvents which are found as volatile impurities and have their limits set by ICH guidelines are depicted in Table 1. Class III solvents, such as acetic acid, acetone, isopropyl alcohol, butanol, ethanol, and ethylacetate should be limited by GMP or other quality-based requirements. Table 1. ICH limits for a selected list of common organic solvents found as volatile impurities. Volatile Organic Impurity Limit (ppm) PDE (mg/day) Acetonitrile 410 4.1 Chloroform 60 0.6 1,4-Dioxane 380 3.8 Methylene chloride 600 6.0 Pyridine 200 2.0 1,1,2-Trichloroethane 80 0.8 USP <467> 2009 General Chapter contains a more comprehensive method for residual solvent analysis that is similar to the ICH guidelines developed in 1997. Here, a limit test is prescribed for class 1 and class 2 solvents while class 2C solvents are usually determined by non headspace methods due to their higher boiling point. The limits of detection (LOD) recommended for class 3 solvents are up to 5000 ppm. When the levels of residual solvents exceed USP or ICH limits, quantitation is required. NOTE: Regulatory limits for impurities mentioned in this document are given as examples and may not provide the complete information needed.

Impurity profiling processes usually begin with the detection of impurities, followed by their isolation and characterization. For all three types of impurities, it is critical to develop a robust method during process development that can eventually be validated and transferred to QA/QC. Developing reliable methods for impurities regulated at very low levels, such as genotoxic impurities, adds further challenges to this process. To better detect, identify, quantify, and characterize the impurities present in drug substances and products, pharmaceutical scientists rely on fast analytical tools with high sensitivity and specificity. Major analytical tools for impurity analysis include spectroscopy, chromatography, and various combinations of both, i.e. tandem techniques. The appropriate technique is selected based on the nature of the impurity and the level of information required from the analysis. There are various complex analytical problems in pharmaceutical development that require the use of more than one analytical technique for their solution. Analytical techniques such as LC/UV, LC/MS, GC/MS, CE/MS, and LC/UV provide the orthogonal detection and complementary information that can address these challenges in a time efficient manner. As a result, they play a vital role in impurity profiling of pharmaceuticals from identification to the final structure elucidation of unknown impurities. Table 2 summarizes of some of the techniques used in impurity analysis. Further details on key single and tandem techniques for impurity profiling are found in the section that follows. Table 2. Impurity analysis techniques. Type of Impurity Technologies Organic impurities FTIR, Preparative LC, LC/UV, LC/MS (SQ, Q-TOF, and QQQ), CE, SFC, and NMR Inorganic/elemental impurities ICP-OES and ICP-MS Residual solvents GC and GC/MS See sections below for definitions of abbreviations. 8 Fourier Transform Infrared Spectroscopy (FTIR) FTIR is very helpful for identifying and confirming the structure of an impurity or degradant because it provides a complex fingerprint that is specific to a particular compound. An FTIR spectrum of an organic molecule is determined by the functional groups present. The technique helps to identify the structure and measure the concentration of the compound under investigation. Changes in the structure can be correlated with the help of an FTIR spectrum of a patent drug compared to that of the impurity or degradant. Agilent Cary 630 FTIR Figure 1. Agilent MicroLab software displays analysis results for the level of ethylene glycol, an impurity in glycerol. The red color band shows that the level of impurity is outside specification range. See Agilent publication 5990-7880EN. The Agilent Cary 630 FTIR packs a powerful combination of precision and compliance, making it one of the best FTIR systems for routine analysis in pharmaceutical laboratories. Measuring contaminants, such as ethylene glycol and diethylene glycol in glycerol, is quick and easy with the 630 FTIR, because its DialPath accessory reduces the tedious process of finding the right path length and optimum measurement conditions. In addition, Agilent MicroLab software makes it easy to meet regulatory requirement 21 CFR 11 by alerting users when the impurity level is outside specification range (Figure 1), while proprietary liquid analysis technology simplifies sampling and reduces the risk of user error. Preparative Liquid Chromatography (LC) Since the impurities in the drug substance are usually present at very low quantities, detailed analysis is only possible upon isolation of the impurities. However, this is a major challenge in pharmaceutical laboratories. Preparative LC helps isolate impurities (usually from impurity-enriched analytes, such as the solution remaining from the crystallization of APIs) in sufficient quantities to carry out structural analysis, usually using techniques such as FTIR, NMR, LC/MS, or GC/MS. Agilent 1260 Infinity Purification Systems 9 Liquid Chromatography and Ultraviolet Spectrometry (LC/UV) Agilent 1200 Infinity Series LC Systems and columns A number of impurity analysis methods found in pharmaceutical quality control (QC) laboratories use high-performance liquid chromatography (HPLC) coupled with UV detection (HPLC/UV methods). UV spectrometry helps identify impurity or degradants in drug substances based on absorption maxima. This technique is one of the most important and versatile analytical methods available for impurity profiling today due to its high selectivity (i.e., ability to quantitatively determine a number of the individual components present in a sample using a single analytical procedure), especially for routine analysis where standards are available. Newer, stationary phase systems are available which operate in several modes, such as ion pairing, increased hydrophobic interactions, and variable pH, allowing a variety of samples to be analyzed concurrently based upon their unique properties. High resolution is particularly helpful when using LC/UV analysis for impurity detection, because all impurities can be identified with less chance of error. Figure 2 demonstrates the results achieved using an Agilent LC system combined with Agilent 1.8 μm RRHD columns identifying and quantifying seven impurities. Isocratic Impurity Method Column: 4.6 x 150 mm, 5 µm mAU 2.5 2 1.5 1 0.5 0 -0.5 -1 0 5 4.6 x 150, 5 µm Rs = 1.15 G/N = 42 4 impurities baseline not separated for 2 10 15 20 4.6 x 150, 3.5 µm Rs = 1.37 S/N = 50 7 impurities baseline not separated for 6 min 4.6 x 150, 1.8 µm Rs = 1.80 (+57 %) S/N = 44 7 impurities baseline separated for all Figure 2. This data demonstrates the value of UHPLC systems, like the Agilent 1290/1260/1220 Infinity Series systems, for impurity analysis. When combined with Agilent 1.8 μm RRHD columns, it was possible to identify all seven impurities with good baseline separation for accurate quantification. Agilent Technologies, unpublished data. 10 Liquid Chromatography and Mass Spectrometry (LC/MS) 6100 Series Single Quad 6500 Series Q-TOF 6400 Series Triple Quad Agilent Mass Spectrometers Capillary Electrophoresis (CE) Agilent 7100 CE instrument LC/MS is a powerful analytical tool that is routinely used in pharmaceutical development to test and identify product impurities. The detection limit of a few hundred ppm is readily achievable, ensuring the identification of all the impurities present at concentrations greater than 0.1 %. MS-based methods generally provide additional robustness and ruggedness compared to techniques such as UV alone, due to their high specificity and sensitivity. While single quadrupole mass spectrometers work well as analytical tools for the confirmation of known impurities and the preliminary structural assessment of unknown impurities, highly sensitive Q-TOF mass spectrometers provide higher resolution and mass accuracy that enables the unambiguous identification of unknown trace impurities, making them very useful for genotoxic impurity analysis. MS-based methods are often selected for the impurity profiling of APIs during process development, while UV-based methods are generally used to test for genotoxic impurities in QC laboratories at manufacturing sites. Triple-quadrupole (QQQ) LC/MS/MS systems have become a standard platform for the quantitative analysis of organic impurities in pharmaceutical analytical laboratories. Combining multiple reaction monitoring (MRM) with a triple quadrupole tandem mass spectrometer, such as the Agilent 6400 Series QQQ, enables extraordinary sensitivity for multi-analyte quantitative assays. MRM assays are particularly useful for the targeted analysis of compounds present in complex mixtures and matrices, such as blood. The determination of drug-related impurities is currently the most important task for CE within pharmaceutical analysis because it achieves high separation efficiencies compared to other chromatographic techniques. CE can be employed when HPLC techniques are not able to adequately measure impurities, especially in the case of very polar compounds. A detection limit of 0.1 % is widely accepted as a minimum requirement for a related impurities determination method and this can be achieved using CE. In addition, CE is very useful for the separation of closely related compounds, such as diastereomers and enantiomers. An example of the value of CE in impurity analysis can be demonstrated using heparin (a polymeric anticoagulant) as an example. In this case, standard chromatography failed to distinguish drug lots associated with adverse events while CE was easily able to identify an unknown impurity (Figure 3). As a result, the use of CE helped to solve this analytical challenge. mAU 60 50 40 30 20 10 0 2 4 6 8 min Figure 3. Capillary electrophoresis of heparin and related impurities using highly concentrated buffers in a 25μm bubble cell capillary. See Agilent publication 5990-3517EN. 11 Supercritical Fluid Chromatography (SFC) SFC, which uses supercritical CO2 as mobile phase, is another orthogonal technique that can be used for impurity detection because it offers HPLC-level sensitivity with reduced organic solvent usage (Figure 4). SFC also offers the advantage of chiral impurity analysis enabling the determination of enantiomeric excess at very low impurity levels (Figure 5).

See Agilent publication 5990-5969EN. 12 Nuclear Magnetic Resonance Spectroscopy (NMR) NMR is a powerful analytical tool that enables the study of compounds both in solution and in the solid state. It has wide applicability because it provides specific information about bonding and stereochemistry within a molecule, which is particularly important in the structural characterization of drug impurities and degradants often present only in extremely limited quantities. The non-destructive, non-invasive nature of NMR spectroscopy makes it a valuable tool for the characterization of impurities and degradants present at very low levels. NMR can also provide quantitative output, an important aspect of impurity profiling. 400-MR DD2 Magnetic Resonance System Inductively-Coupled Plasma Optical Emission Spectroscopy (ICP-OES) and Inductively-Coupled Plasma Mass Spectrometry (ICP-MS) Agilent 720 and 730 ICP-OES Agilent 7700 Series ICP-MS The new draft elemental impurities procedure (USP<233>) requires that an instrument-based method is used to determine elemental impurities and that the reference methods are based on either ICP-MS or ICP-OES. With both methods, sample analysis can be accomplished in three ways: directly (unsolvated), following sample preparation by solubilization in an aqueous or organic solvent, or after acid digestion using a closed-vessel microwave system. ICP-OES ICP-OES provides parts per billion (ppb) detection limits for most regulated elements in pharmaceutical products, easily meeting the specified limits in cases where direct sample analysis or small dilution factors are appropriate. It also provides extended dynamic range, robust plasma, and one-step measurement of major, minor, and trace elements. Therefore, ICP-OES addresses the needs of a wide range of users, including those seeking a cost-effective solution for the direct analysis of elemental impurities in bulk raw materials and pharmaceutical products. ICP-MS ICP-MS is a powerful and sensitive technique that delivers a reliable trace-level analysis of all 16 elements whose limits are defined in USP<232>. The low detection limits of ICP-MS ensure that all regulated elements in drug substances or drug products can easily be determined using the new method, at or below regulated levels, and even when large sample dilutions are required. ICP-MS can also be used in combination with a variety of separation techniques, such as HPLC, GC, and CE, providing several options for separation (or speciation) of the different chemical forms of the elements, and depending upon the nature of sample. ICP-MS achieves low detection limits for almost all elements, including those found in the more extensive analyte list proposed in the ICH Q3D, such as Au and Tl. 13 Gas Chromatography (GC) 7890A/5975C GC/MS system with 7697A Headspace sampler GC columns 14 In combination with flame ionization detection (FID), GC is the standard choice for the analysis of volatile organic impurities, such as residual solvents. The gas chromatography headspace method is used worldwide for residual solvent analysis in quality control laboratories because it closely follows ICH Q3C guidelines. Sample preparation and introduction is via a static headspace which facilitates the selective introduction of volatile solvents without contamination by mostly non-volatile drug substance or drug products. Therefore, the use of an FID detector helps preferentially identify and quantify residual solvents. More recently, the combination of gas chromatography and mass spectroscopy (GC/MS) has been successfully used for confirmation and identification purposes, highlighting the flexibility of this technology. A SELECTION OF AGILENT APPLICATION SOLUTIONS FOR THE THREE MAJOR TYPES OF IMPURITIES Overview 3 This section includes a selection of detailed examples of Agilent applications solutions that have been developed to meet the challenges encountered when analyzing the three types of pharmaceutical impurities: the qualitative and quantitative analysis of trace level organic impurities, the determination of elemental impurities, and the analysis of residual solvents according to USP procedures. 3.1 ANALYSIS OF ORGANIC IMPURITIES • Achieve precision, linearity, sensitivity, and speed in impurity analysis with the Agilent 1200 Infinity Series HPLC/UV solutions • Improve profiling productivity for the identification of trace-level impurities using Agilent LC/Q-TOF solutions • Quantitative analysis of genotoxic impurities in APIs using Agilent LC/QQQ solutions 3.2 ANALYSIS OF INORGANIC IMPURITIES • Determination of elemental impurities in pharmaceutical ingredients according to USP procedures by Agilent ICP-OES and ICP-MS based solutions 3.3 ANALYSIS OF RESIDUAL SOLVENTS • Faster analysis and enhanced sensitivity in residual solvent analysis as per USP <467> procedures using Agilent GC based solutions 15 ANALYSIS OF ORGANIC IMPURITIES Agilent 1200 Infinity Series LC/UV Systems are an ideal solution for impurity analysis in pharmaceutical quality control laboratories seeking to achieve the necessary precision, linearity, sensitivity, and speed required to meet the regulatory standards for impurity analysis. The example shown in Figure 6 is for the analysis of amoxicillin and its impurities. This analysis was completed within 7 minutes and detected impurities down to a level of 0.01 %. Excellent precision of retention times, peak areas, and linearity was achieved with a correlation coefficient of R2 > 0.999 (Figure 7) for five impurities. mAU 8 Amoxicillin Achieve precision, linearity, sensitivity, and speed in impurity analysis with the Agilent 1200 Infinity Series LC Impurity A 3.1 Impurity E 6 2 Impurity D Impurity C Impurity B 4 0 0 0.5 1 1.5 2 2.5 3 3.5 4 4.5 min Figure 6.

The impurities in amoxicillin are measured with excellent linearity at six concentration levels. See Agilent publication 5990-6093EN. 16 Agilent’s UHPLC/UV solutions help achieve higher sensitivity, faster sample throughput, and significant cost savings in impurity profiling. Since the 1290 Infinity LC can be operated at up to 1200 bar pressure, using a very sensitive DAD detector, significantly faster methods can be developed for profiling impurities in a highly productive manner. This leads to a significant reduction in the cost per analysis. The Agilent Multi-Method solution for LC is ideally suited for testing experimental conditions, such as determining the ideal combination of stationary and mobile phases. It makes scouting stationary and mobile phases a simple, automated task, especially when short run times are used (e.g., a few minutes on an Agilent 1260 or 1290 Infinity LC). The Agilent Intelligent System Emulation Technology (ISET) can be used when there is a need to transfer the final method optimized on UHPLC to standard HPLC equipment and columns, especially in regulated QA/QC environments. ISET can be used to execute new or legacy HPLC methods, delivering the same chromatographic results without the need to change the original method or modify the instrument hardware. Other HPLC or UHPLC System 1100 Series LC 1200 Series LC 1290 Infinity LC with ISET Method Transfer 1220 Infinity LC 1260 Infinity LC Figure 8. Agilent’s ISET system can be used to efficiently transfer methods from a range of systems to the final QC environment. See Agilent publication 5990-8670EN. 17 The advantage of using ISET’s seamless method transfer for impurity analysis is demonstrated in Figure 9. After a method was developed for the analysis of paracetamol and its impurities on the Agilent 1290 Infinity LC, the ISET tool emulated the target LC, an Agilent 1100 Series Quaternary LC System, to determine whether the method that had been developed was suitable for that system. The method was then transferred to the 1100 Series LC System. The three chromatograms obtained on the 1290 Infinity LC System, with and without ISET, and those obtained on the 1100 Series quaternary LC System are compared in Figure 9. mAU 30 25 20 Agilent 1290 Infinity LC System without emulation 15 Agilent 1290 Infinity LC System using ISET to emulate the 1100 Series Quaternary LC 10 Agilent 1100 Series Quaternary LC System 5 0 2 4 6 8 10 Time (min) 12 14 16 18 Figure 9. Overlay of chromatograms at 270 nm obtained for paracetamol and its impurities on the Agilent 1290 Infinity LC System (blue), the Agilent 1290 Infinity LC System with ISET (orange), and on the Agilent 1100 Series Quaternary LC System (black). See Agilent publication 5990-9715EN. In addition to LC systems, LC columns can significantly impact the results achieved in organic impurity profiling. For example, laboratories performing compendia analysis with conventional, long, 5 µm totally porous LC columns can benefit from the increased speed, resolution, and sensitivity that superficially porous, Agilent Poroshell 120 columns provide, without having to replace existing instrumentation. Since USP and EP guidelines allow for method flexibility in reducing column length and particle size, transferring methods to shorter 2.7 µm Poroshell 120 columns can save significant time, while maintaining performance in the separation. This results in higher throughput and greater productivity with Agilent Poroshell 120 columns than can be achieved with conventional 5 µm columns (Figure 10). 18 3.917 0.365 0.677 0.606 10 1.231 mAU 2.0 mL/min 4.6 × 75 mm Agilent Poroshell 120 EC-C18 0 10 15 5.186 10 1.617 0.482 0.798 5 0.890 0 mAU 20 25 min 1.5 mL/min 4.6 × 75 mm Agilent Poroshell 120 EC-C18 10 15 7.748 2.406 20 4.6 × 75 mm Agilent Poroshell 120 EC-C18 0 0 10 15 20 25 min 5 9.448 4.6 × 250 mm Agilent Eclipse Plus C18 5 µm 4.693 4.406 5 2.182 2.3112.433 2.632 3.018 3.194 0 10 min 1.0 mL/min 0 mAU 25 24.728 10 5 1.327 0 mAU 0.660 0.690 0.715 0.844 1.188 0 1.0 mL/min 10 15 20 25 min Figure 10.

Software can also assist in a number of key tasks required for impurity profiling. For example, Agilent OpenLAB ELN guides chemists through the complete workflow and documents all data in a central and secure repository that meets regulatory standards. Agilent OpenLAB Chromatography Data Software (CDS) software also offers builtin peak purity evaluations (Figure 11) and lets you generate your final impurity profile report right from the CDS. By comparing spectra from the upslope, apex, and downslope, impurities present at less than 0.5 % can be identified. This can and should be done as a matter of routine to achieve reliable high-quality data. Custom calculation functionality in this analytical software helps calculate the total level of impurities for a complete run and includes a PASS/FAIL notification against user-definable limits depending on the toxicity class of the impurities. 5% 0.5 % 0.1 % Figure 11. ChemStation peak purity software can be used to determine impurities present at less than 0.5 %, based on spectral differences. See Agilent publication 5988-8647EN. 19 Improve profiling productivity for the identification of tracelevel impurities using Agilent LC/Q-TOF solutions The Agilent 6540 Q-TOF delivers sensitive MS and MS/MS analysis of trace level impurities in drug substances with sub-ppm mass accuracy. The workflow shown in Figure 13 uses advanced MassHunter data analysis features like molecular feature extraction (MFE) and molecular formula generation (MFG), along with molecular structure correlator (MSC) software. The effective use of this novel workflow for impurity profiling is demonstrated by the rapid identification and structural elucidation of atenolol and eight impurities (present at > 0.01 % relative to the API’s UV detection area) as shown in Figure 14. A unique feature of MSC software helps elucidate the structure of impurities in an efficient manner. This workflow is streamlined to provide high confidence, accurate identification and faster structure elucidation compared to conventional impurity profiling which requires multiple platforms and spreads analysis over multiple days. If the method is not MS compatible HPLC Separation If the method is MS compatible LC/MS analysis using Agilent 6540 Q-TOF with full MS scan followed by auto MS/MS Find and identify impurities by MFE and MFG based on the accurate mass MS data MSC facilitates the structure elucidation of the impurities Develop equivalent MS Compatible LC method Result Ex. 1 m/z: 268.1543 2 C14H21NO4 3 Figure 13.

Agilent publication in development. Quantitative analysis of genotoxic impurities in APIs using Agilent LC/QQQ solutions The Agilent 1200 Infinity Series LC and Agilent 6400 Series Triple Quadrupole (QQQ), in combination with Agilent columns and MassHunter software, provide a dependable solution for the quantitative analysis of genotoxic impurities at the lower detection limits required by current regulations. Variations in organic modifier, and column stationary phases and dimensions, can be used to tune the selectivity, peak capacity, and peak resolution. This generic approach can be applied in early method development or used for potential genotoxic impurity screening procedures prior to method optimization. MRM-based quantitation of nine arylamine and aminopyridine potential genotoxic impurities (PGIs) at trace levels (well below 1 ppm relative to the API) using an Agilent 1290 Infinity Series LC coupled to an Agilent 6400 Series QQQ is demonstrated in Figure 15. Detection limits for these nine PGIs were below 20 ppb (relative to the API) using MS/MS. Selectivity in the presence of related impurities was assured through the use of specific quantifiers and qualifiers for each PGI. All nine PGIs were well separated within 9 minutes using an Agilent 150 mm ZORBAX Eclipse Plus C18 RRHD column (2.1 mm id, 1.8 μm). Analysis time can be further reduced to 3 minutes by using a 50 mm Agilent ZORBAX Eclipse Plus C18 RRHD column. One of the PGIs (2,6-dichloroaniline) was quantified using a diode array detector (DAD) at a detection level of 100 ppb relative to the API. The recoveries calculated by comparison of a standard solution of the PGIs provided accuracy levels of 70 %- 130 %, which are typical limits in pharmaceutical trace analysis procedures (e.g., limit tests). 21 A mAU Chlorhexidine, spiked with 1 ppm PGIs DAD 260 nm 40 30 20 10 0 2 3 4 5 6 7 min PGI 5, 166.1>130.0 (80.4%) 1 0 1 PGI 4, 163.1>120.0 (98.3%) B 0 ×10-2 1 PGI 6, 150.1>108.0 (3.8%, coelution with API) 2000 PGI 5, 166.1>130.0 0 PGI 3, 136.1>121.0 (101.7%) 0 ×10-1 1 PGI 4, 163.1>120.0 1000 ×10-1 1 1000 PGI 6, 150.1>108.0 PGI 7, 129.1>93.0 (79.1%) 2000 PGI 3, 136.1>121.0 0 ×102 1 500 PGI 8, 128.1>93.0 (Present in API, > 20 ppm) PGI 7, 129.1>93.0 0 1000 ×10-2 1 PGI 8, 128.1>93.0 PGI 2, 126.1>111.0 (96.0%) 0 PGI 2, 126.1>111.0 100 ×10-1 1 PGI 9, 122.1>105.1 (98.5%) PGI 9, 122.1>105.1 500 0 ×10-2 1 PGI 1, 119.1>92.0 (89.6%) PGI 1, 119.1>92.0 250 0 2 3 4 5 6 Counts (%) vs. Acquisition Time (min) 7 0.8 1 1.2 1.4 1.6 1.8 2 Counts vs. Acquisition Time (min) 2.2 2.4 Figure 15.

The robust plasma system on the Agilent 700 Series ICP-OES is capable of analyzing the most challenging samples, such as undiluted organic solvents and concentrated salt solutions, to enable fast, accurate analysis which is free of complex sample digestion procedures (See Figure 16). 6 PPM 4 2 As 188.980 Cr 267.716 Co 238.892 Se 196.026 Ba 455.403 Mn 257.610 Sr 407.771 Zn 213.857 0 0 30 60 90 120 150 180 210 Time (min) Figure 16. The robust plasma system of the Agilent 700 Series ICP-OES ensures the stable analysis of difficult samples, such as the 5 % NaCl brine solution shown here. Agilent Technologies, unpublished results. In combination with closed-vessel microwave digestion and sample stabilization using HCl, the Agilent 7700x ICP-MS has been shown to be capable of determining all regulated elements at low levels in typical pharmaceutical sample digests (See Agilent publication 5990-9365EN). Simple method development and routine operation are provided by the standard helium (He) mode method, which uses a single set of consistent instrument operating conditions for all analytes and samples. As required in USP<233>, unequivocal identification and verification of analyte results is also provided by the secondary (qualifier) isotopes measured in He mode. Low limits of detection are particularly important for potentially toxic trace elements defined in USP<232>, notably As, Cd, Hg, and Pb. Calibrations for these elements in He mode are shown in Figure 17, together with Pd and Pt, which are representative members of the platinum group elements (PGEs) that must be monitored when added as catalysts as per USP<232>. 24 System performance validation of the 7700x ICP-MS delivered data that was easily within method requirements for accuracy, stability, and spike recovery at detection limits that were all several orders of magnitude lower than the levels at which the trace elements are currently controlled. This provides the reassurance that the Agilent 7700x will be able to meet the regulatory requirements for pharmaceutical materials regulated under USP methods, even if control limits are made more sensitive in the future. The Agilent 7700x also provides a full mass spectrum screening capability, is tolerant of all commonly-used organic solvents, and can be linked to a chromatography system to provide integrated separation and analysis of the different forms of As and Hg, as required under USP<232>. 75 As [He] ISTD: 45 Sc [He] 111 Cd [He] ISTD: 159 Tb [He] x10–1 R = 0.9998 201 Hg [He] ISTD: 209 Bi [He] x10–3 R = 0.9999 x10–2 R = 0.9999 1.5 Ratio Ratio Ratio 1 2 0.5 1 0.5 As Cd Hg 0 0 5.0 10.0 Conc (ppb) 0 2.0 4.0 Conc (ppb) 15.0 208 Pb [He] ISTD: 209 Bi [He] 5.0 10.0 Conc (ppb) 105 Pd [He] ISTD: 159 Tb [He] x10–1 R = 0.9999 195 Pt [He] ISTD: 209 Bi [He] x10–1 R = 0.9999 3 1 x10–1 R = 0.9999 Ratio 5 Ratio Ratio 2 0.5 15.0 1 Pb 0 Pd 5.0 Conc (ppb) 10.0 Pt 0 0 5.0 Conc (ppb) 10.0 5.0 Conc (ppb) 10.0 Figure 17.

Agilent Elemental Impurity Analysis Publications Publication Number 5990-5427EN 5990-9365EN 5990-9382EN 5990-9073EN Title Pharmaceutical analysis by ICP-MS: new USP test for elemental impurities to provide better indication of potentially toxic contaminants Validating the Agilent 7700x ICP-MS for the determination of elemental impurities in pharmaceutical ingredients according to draft USP general chapters <232>/<233> Proposed new USP general chapters <232> and <233> for elemental impurities: The application of ICP-MS for pharmaceutical analysis Regulatory compliance for ICP-MS 25 3.3 RESIDUAL SOLVENT ANALYSIS Faster analysis and enhanced sensitivity in residual solvent analysis as per USP <467> procedures using Agilent GC-based solutions Quality assurance laboratories routinely use United States Pharmacopeia (USP) method <467> for residual solvent analysis. The Agilent 7697A Headspace Sampler coupled to an Agilent 7890 GC offers a very efficient solution for the analysis of UPS<467> class 1 and class 2 residual solvents at their limit concentrations in aqueous solutions. USP<467> specifies three procedures for class 1 and class 2 residual solvents: 1. Procedure A: identification and limit test 2. Procedure B: confirmatory test (if solvent is above limit) 3. Procedure C: quantitative test Procedure A uses G43 phase Agilent 624 columns (VF-624ms or DB-624) and Procedure B uses a G16 phase (HP-INNOWax) column. In general, analytes that co-elute in one of these phases do not co-elute in the other. As demonstrated in Figures 18 and 19, the Agilent 7697A Headspace sampler is capable of outstanding repeatability for the analysis of residual solvents. Repeatability is better than 2.5 % relative standard deviation (RSD) for class 1, class 2A, and class 2B solvents. An inert sample path, thermal zones with set point stability of better than +/- 0.1 °C, and EPC-controlled vial sampling using absolute pressure, all contribute to system performance. Carryover is essentially non-existent in all configurations. User programmable flow rates and times, needle/loop purges, and vent line purges are effectively used to clean the system between runs. Laboratories should perform system suitability studies and validate their proposed methods according to USP or ICH guidelines. For new drug development and quality control, a dual-channel configuration using both FID and a mass selective detector (MSD) is a powerful tool for residual solvent determinations, especially when unknown identification or confirmation is needed. This system is particularly well-suited for the development of generic methods that do not need to follow USP<467> guidelines. MSD analysis also helps avoid ambiguity, as over 60 solvents are currently used in pharmaceutical manufacturing. When unknown peaks or solvents are present, this system may be the best solution for confirmation and quantitation. 26 A 1. 2. 3. 4. 5. 4 1,1-dichlorothene 1,1,1-trichloroethane carbon tetrachloride benzene 1,2-dichloroethane 1 5 2 3 B 10 13 14 12 5 3 8 11 6 9 2 1 C 1. 2. 3. 4. 5. 6. 7. 8. 7 4 1. methanol 2. acetonitrile 3. dichloromethane 4.
