• Uses: Used for synthesis of pharmaceutical intermediates. Used as a reactant in the preparation of pyrimidinone ribosides and analogs that show anti-tumor properties. N,O-bis(trimethylsilyl)-trifluoroacetamide (BSTFA) is similar to BSA in specificity of modification and there are several studies which have used both reagents.One study found BSTFA superior to BSA in product stability and yield of derivative. Another study compared several trimethylsilyl donors for end-capping of silica and observed that BSTFA was more reactive than BSA but less reactive than TMCim. Both BSA and BSTFA were used to prepare trimethylsilyl derivatives of pyrimidines and purines.Current work has used BSTFA for metabolomics analysis of urine,for the measurement of khatamines (psychoactive amines of khat (Catha edulis Forsk), and for the measurement of acrylamide in cocoa. N,O-Bis(trimethylsilyl)trifluoroacetamide is used for analytical purposes or as a chemical reagent for synthesis of more complex molecules. It is silylation reagent useful in GC and GC-MS for the derivatization of a wide range of functional groups under mild conditions. It is also used as DAT inhibitor and a SLC6A2 inhibitor. It is routinely used to derivatize carboxylic acids, phenols, steroids, amines, alcohols, and alkaloids and amides.
