Used as a chiral building block in the synthesis of pharmaceuticals, particularly in the production of enantiomerically pure compounds. It plays a crucial role in the development of active pharmaceutical ingredients (APIs) for drugs targeting central nervous system disorders. The compound is also employed in asymmetric synthesis to create intermediates for antibiotics and other therapeutic agents. Its tartrate salt form enhances stability and solubility, making it suitable for use in various organic reactions and drug formulation processes.
