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, especially for dopamine and serotonin receptors, making it valuable in researching antipsychotic and antidepressant drugs. The nitrile group and chiral piperazine backbone allow for further functionalization and improved binding selectivity. It is also employed in the preparation of bioactive molecules where stereochemistry plays a critical role in pharmacological activity.
