Used as a key intermediate in the synthesis of pharmaceutical agents, particularly in the development of central nervous system (CNS) active compounds. Its structure supports the creation of selective receptor modulators, including those targeting dopamine and serotonin receptors. Commonly employed in research for antipsychotic and antidepressant drug candidates. The benzonitrile group and piperidine moiety together enhance binding affinity and metabolic stability, making it valuable in medicinal chemistry for optimizing lead compounds. Also utilized in the preparation of radiolabeled derivatives for receptor binding studies.
