Acetic anhydride is a reagent that is used in the
manufacturing of acetyl compounds and cellulose
acetates. It is also utilized as a solvent in the
examination of wool fat, glycerol, fatty and volatile oils,
1
and resins. In the synthesis of organic compounds,
acetic anhydride is used in various reactions, including
the cleavage of dialkyl ethers, the formation of
anhydrides from carboxylic acids, the addition of
methylthiomethyl groups to phenol rings, and the
addition of acyl and acyloxy groups across double
bonds. Acetic anhydride will also react with such
2
acetals, alcohols, and sulfoxides.
A wide variety of substrates and materials has been
synthesized using acetic anhydride. Small molecule
syntheses include the preparation of substituted
2-pyridones, acylated silyl ketene acetals, and
estrogen receptor ligands derived from
3,4,5
2,3-diarylpiperazines.
Larger materials which have
been prepared with acetic anhydride include cellulose
and poly(ethylene oxide)-block-poly(N-hexyl-L6,7
aspartamide)-acyl conjugates.
Acetic anhydride has been used to hyperacetylate
histones to investigate transcriptional effects of the
NAD-dependent histone deacetylase Sir2 in
Drosophila on a complex of the hyperacetylated
8
histones with DNA. An affinity chromatography/mass
spectrometry method for the analysis of
neuroendocrine peptides from carboxypeptidase E
9
deficient mice has been reported.
A microarray of oligonucleotide probes linked to a solid
support that uses acetic anhydride in the preparation
10
has been described. Acetic anhydride is utilized in
an assay of a fluorescently labeled peptide catalyst
library for application to the resolution of secondary
11
alcohols.
Precautions and Disclaimer
For Laboratory Use Only. Not for drug, household or
other uses.
Preparation Instructions
This product is miscible in chloroform and ether. In
alcohol, this product will form ethyl acetate. In water
(0.1 ml/ml, v/v), this product will slowly form acetic
1
acid.
