Used in the synthesis of biologically active compounds, particularly in pharmaceutical research targeting central nervous system disorders. Its chiral structure makes it valuable as an intermediate in asymmetric synthesis, where stereochemistry plays a critical role in drug efficacy. Commonly employed in the development of enzyme inhibitors and receptor modulators due to its ability to mimic peptide-like structures. The hydrochloride salt form enhances solubility and stability, facilitating use in aqueous reaction conditions and biological assays.
