Description

Alfa Aesar Trifluoromethanesulfonic anhydride, 98%, Quantity: 250g, Boiling Point: 81 deg.C to 83 deg.C, Melting Point: -80 deg.C, Molecular Weight: 282.127, Percent Purity: 98%, Beilstein: 1813600, CAS: 358-23-6, ChEBI: CHEBI:48509, Density: 1.72 | CAS: 358-23-6 | C2F6O5S2 | 282.127 g/mol

Trifluoromethanesulfonic anhydride is used to convert phenols and imine into triflic ester and NTf group. It is a strong electrophile used for the introduction of triflyl group in chemical synthesis. It serves as a reagent in the preparation of alkyl and vinyl triflates, and for the stereoselective synthesis of mannosazide methyl uronate donors. It acts as a catalyst for glycosylation with anomeric hydroxy sugars to prepare polysaccharides.

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.
