Used as a key intermediate in the synthesis of pharmaceuticals, particularly in the development of central nervous system (CNS) agents and analgesics. Its structure supports the formation of bioactive molecules due to the presence of both amino and cyano functional groups, which can be further modified in multi-step syntheses. Commonly employed in the preparation of gamma-aminobutyric acid (GABA) analogs, which are important for treating neurological disorders such as epilepsy, neuropathic pain, and anxiety. The hydrochloride salt form enhances solubility and stability, making it suitable for use in aqueous reaction environments during drug manufacturing.
