Used primarily in pharmaceutical research as an intermediate in the synthesis of bioactive compounds. It serves as a building block for drugs targeting the central nervous system, including potential antipsychotic and antidepressant agents. Its structural features make it suitable for modifying receptor affinity and improving metabolic stability in drug design. Also investigated for use in developing selective serotonin and dopamine receptor modulators. Commonly employed in the preparation of novel piperazine derivatives for structure-activity relationship studies.
