Applications
Triisopropylsilyl trifluoromethanesulfonate is used as a reagent for the introduction of triisopropylsilyl(TIPS) group in organic synthesis. It is involved in the synthesis of 2-substituted benzothiopyran-4-ones and silyloxy acetylenes. As a protecting group in organic synthesis, it is utilized especially for the protection of primary amines. Furthermore, it plays an important role in Takahashi Taxol total synthesis or for chemical glycosylation reactions.

Solubility
Miscible with chloroform and ethyl acetate.
