TECHNICAL DATA SHEET 14 C Caution: For Laboratory Use. A product for research purposes only ASPARTIC ACID, L-[ 14C(U)]Product Number: NEC-268E LOT SPECIFIC INFORMATION Production date Lot Number: Specific Activity: 5-May-2010 3570166 200 7.4 mCi/mmol GBq/mmol M.W. 133.1 C4H7NO4 CAS 56-84-8 PACKAGING: 0.1 mCi/ml (3.7 MBq/ml) in water : ethanol (98:2), steri-packaged. Shipped ambient. STABILITY AND STORAGE: When aspartic acid, L-[14C(U)]- is stored at 5oC in its original solvent and at its original concentration, the rate of decomposition is initially 2% per year from the date of purification. The rate of decomposition can accelerate. Stability is nonlinear and not correlated to isotope half-life. Lot to lot variation may occur. SPECIFIC ACTIVITY RANGE: >200 mCi/mmol (>7.41GBq/mmol) RADIOCHEMICAL PURITY: This product was initially found to be greater than 97% when determined by the following method. It is advisable to check purity prior to use. High performance liquid chromatography on a SCX column using the following mobile phase: 10 mM potassium phosphate pH 3.0 OPTICAL PURITY: This product was determined to be greater then 97% L-aspartic acid. QUALITY CONTROL: The radiochemical purity of aspartic acid, L-[14C(U)]- is checked at appropriate intervals using the above chromatography method. HAZARD INFORMATION: WARNING: This product contains a chemical known to the state of California to cause cancer.
