Description

Trifluoromethanesulfonic acid acts as a catalyst for esterification reactions and an acidic titrant in nonaqueous acid-base titration. It is useful in protonations due to the presence of conjugate base triflate is non nucleophilic. It serves as a deglycosylation agent for glycoproteins. In addition, it is a precursor and a catalyst in organic chemistry. It reacts with acyl halides to prepare mixed triflate anhydrides, which are strong acylating agents used in Friedel-Crafts reactions. It acts as a key starting material for the preparation of ethers and olefins by reacting with alcohols as well as to prepare trifluoromethanesulfonic anhydride by dehydration reaction.

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.
