Used as a key intermediate in the synthesis of pharmaceuticals, particularly in the development of protease inhibitors and other biologically active compounds. Its structure supports the construction of peptide-like molecules, making it valuable in medicinal chemistry for designing drugs targeting neurological disorders and metabolic diseases. Also utilized in research settings for creating enzyme substrates and probes to study amino acid transport systems. The hydrochloride salt form enhances solubility and stability, facilitating its use in aqueous reaction environments.
