Description

Application

Catalyst for synthesis of Bacteroides fragilis zwitterionic polysaccharide Ai tetrasaccharide repeating unit via glycosylation

Reagent for stereoselective synthesis of mennosazide methyl uronate donors

Activator for direct glycosylation with anomeric hydroxy sugars

Trifluoromethanesulfonic anhydride solution is generally used to convert hydroxyl groups to triflic esters. It can be used to prepare triflic azide for azido amino acid synthesis.
