Used as a chiral intermediate in the synthesis of pharmaceuticals, particularly in the development of active pharmaceutical ingredients (APIs) where stereochemistry plays a critical role in biological activity. Its structure allows for selective binding and improved efficacy in target drug molecules. Commonly employed in the preparation of central nervous system (CNS) agents and anti-inflammatory compounds. The hydrochloride salt form enhances stability and solubility, making it suitable for use in multi-step organic syntheses under controlled conditions.
