Description

CAS: 4659-45-4 | C7H3Cl3O | 209.45 g/mol

2,6-Dichlorobenzoyl chloride acts as an important intermediate in organic synthesis, pharmaceuticals, agrochemicals and dyestuffs. It is employed in the substrate activity screening method for the rapid development of novel substrates and their conversion into non-peptidic inhibitors of Cys and Ser proteases. It is also used in the preparation of 1-acyliridoles and (-)-aspicilin. In addition to this, it undergoes esterification of (fluoren-9-ylmethoxy)carbonyl (Fmoc)-amino acids to 4-alkoxybenzyl alcohol polystyrene.

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.
