Used in pharmaceutical synthesis as a chiral building block for the production of active pharmaceutical ingredients (APIs), particularly in the development of central nervous system (CNS) agents and analgesics. Its piperidine core and chiral purity make it valuable in creating enantioselective drugs. Commonly employed in the preparation of intermediates for antipsychotics, antidepressants, and anti-addiction medications. Also utilized in asymmetric synthesis due to the tartrate salt enhancing solubility and crystallinity during purification steps.
