Description

2-Chloro-1,3-dimethylimidazolium tetrafluoroborate is a reagent for esterification of C-terminal amino acids to Wang resin without racemization and for coupling α,α-dimethyl amino acids; and for preparation of the benzotriazol-1-yloxy derivative, a new coupling reagent. It is used as a reagent for esterification and peptide coupling of sterically hindered amino acids; preparation of efficient diazo-transfer reagents; oxidative insertion for palladium and nickel catalyst synthesis; and preparation of catalysts for use in coupling 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.
