Used as a chiral building block in the synthesis of pharmaceuticals, particularly in the development of active pharmaceutical ingredients (APIs) requiring stereochemical control. Its structure serves as a key intermediate in the production of certain central nervous system agents and bioactive molecules. The hydrochloride salt form enhances stability and solubility, making it suitable for use in multi-step organic syntheses under various reaction conditions. Commonly employed in research and development for asymmetric synthesis and medicinal chemistry applications.
