2-Chloroethylamine hydrochloride is an important fine chemical intermediate. It can be used for the synthesis of fluvoxamine maleate, which is an important antidepressant drug. 2-Chloroethylamine hydrochloride can also be used as the substrate to synthesize 2-(2'-Aminoaryl)oxazolines and their derivatives, which have been studied as ligands for a variety of metal chelates and are known to possess biological activity in both free ligand and chelated forms. Meanwhile, 2-chloroethylamine hydrochloride can be used for chemical modification of chitosan to improve the biological activity of chitosan.
2-Chloroethylamine hydrochloride can also react with hydroxypropyl starch (HPS) to form aminoethyl hydroxypropyl starch (AEHPS), which can react with collagen peptide (COP) by using microbial transglutaminase (MTGase) as biocatalyst to synthesize aminoethyl hydroxypropyl starch collagen peptide (AEHPS-COP). The AEHPS-COP showed a promising potential application in cosmetic, biomedical and pharmaceutical fields with improved in vitro antioxidant activities.
