    Description

    Applications
    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.

    Solubility
    Miscible with dichloromethane. Immiscible with hydrocarbons.

    Notes
    Moisture sensitive. Incompatible with water, strong bases, strong oxidizing agents, acids and alcohols.
