Used as a chiral intermediate in the synthesis of active pharmaceutical ingredients, particularly in the development of central nervous system agents and antipsychotic drugs. Its stereochemistry allows for selective interactions with biological targets, enhancing drug efficacy and reducing side effects. Commonly employed in medicinal chemistry for structure-activity relationship studies due to the presence of functional groups amenable to further modification. Also utilized in the preparation of optically pure piperazine derivatives for research in neuropharmacology.
