Trimethylsilyl trifluoromethanesulfonate is used to prepare powerful Lewis acid, difluoroboron triflate etherate in acetonitrile solvent. It is also used as a reagent in a Dieckmann-like cyclization of ester-imides and diesters. Further, it is used in the conversion of carbonyl compounds to their enol ethers. It is also employed for chemical glycosylation reactions. Its reactivity is similar to trimethylsilyl chloride and is also involved in organic synthesis.

This Thermo Scientific Chemicals brand product was originally part of the Alfa Aesar product portfolio. Some documentation and label information may refer to the legacy brand. The original Alfa Aesar product / item code or SKU reference has not changed as a part of the brand transition to Thermo Scientific Chemicals.
