Used as an intermediate in organic synthesis, particularly in the preparation of pharmaceuticals and fine chemicals. It serves as a protected form of glycine in peptide synthesis, where the benzyl group acts as a protecting group for the amino functionality, allowing selective reactions at other sites. The hydrochloride salt enhances solubility and stability, making it suitable for use in aqueous or polar environments. Also employed in the development of biologically active compounds, including antimicrobial agents and enzyme inhibitors. Its structure mimics natural amino acid derivatives, which can be leveraged in the design of drug candidates targeting metabolic pathways or receptor sites.
