용도

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.

참고

Moisture sensitive. Store in cool place. Keep the container tightly closed in a dry and well-ventilated place Incompatible with strong oxidizing agents and strong acids.

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.
