Used as a chiral building block in the synthesis of pharmaceuticals, particularly in the development of active pharmaceutical ingredients (APIs) with specific stereochemistry. It plays a role in the production of enantiomerically pure compounds, which are critical for drugs targeting neurological and cardiovascular disorders. Its hydrochloride form enhances stability and solubility, making it suitable for use in various organic reactions and drug formulation processes. Additionally, it is employed in research for studying chiral catalysts and asymmetric synthesis methods.
