Description

CAS: 80522-42-5 | C10H21F3O3SSi | 306.415 g/mol

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.

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.
