Application
For the preparation of N- and O-trifluoroacetyl derivatives of a wide range of biologically active compounds for GC analysis. Also used in the oxidation of aldehydes to acids, esters, or amides. Trifluoroacetic anhydride can undergo reaction with deoxyguanosine in pyridine to give the corresponding 6-substituted-2′-deoxyguanosine derivatives. It can also react with urea-hydrogen peroxide complex to generate peroxytrifluoroacetic acid, which can convert aldoximes to nitroalkanes.
