Description and Uses
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.
