L-Asparagine tert.butyl ester hydrochloride

L-Asparagine tert.butyl ester hydrochloride is a protected amino acid ester derived from L-asparagine in which the carboxyl group is converted to a tert-butyl ester and the amino acid side chain contains a primary amide functionality. The molecule bears an amino group on the α-carbon and an amide side chain, while the tert-butyl ester masks the carboxylate as a neutral ester and the hydrochloride form provides an ammonium chloride salt for the amino functionality. It is used as a stepwise building block in amino acid and peptide synthesis and as a substrate-like intermediate for preparing asparagine-containing peptide derivatives under conditions that require controlled handling of the carboxyl group.

Designed for biological research and industrial applications, not intended for individual clinical or medical purposes.
