Used as an intermediate in the synthesis of pharmaceuticals, particularly in the production of beta-amino acid derivatives and chiral building blocks for drug development. Commonly employed in the preparation of active pharmaceutical ingredients (APIs) requiring enantiomerically pure structures. Also utilized in the manufacture of agrochemicals and specialty chemicals where functionalized amino esters are needed. Its hydrochloride salt form enhances stability and solubility in aqueous reaction systems, making it suitable for peptide coupling and other condensation reactions.
