Description

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.
