N,O-Bis(trimethylsilyl)trifluoroacetamide is used as a derivatization reagent for gas chromatography and mass-spectrometry analysis of phenolic acids in fruits. It is also used as a reactant in the preparation of pyrimidinone ribosides and analogs which shows anti-tumor properties. It plays as an important role as a reagent for the regioselective desulfation of polysaccharide sulfates. Furthermore, it is used to prepare trimethylsilyl ethers of carbohydrates and alcohols.
Powerful silylation reagent useful in GC and GC-MS for the derivatization of a wide range of functional groups under mild conditions, similar to N,O-Bis(trimethylsilyl)acetamide, L00183, with the advantage that both the reagent and its by-product, trifluoroacetamide, are more volatile than the corresponding non-fluorinated analogues: Biochem. Biophys. Res. Commun., 31, 616 (1968). See Appendix 4.
