Used primarily in pharmaceutical research as a key intermediate in the synthesis of bioactive compounds. It serves as a structural scaffold in developing drugs targeting central nervous system disorders, including antipsychotics and antidepressants. Its piperazine and piperidine moieties enhance binding affinity to various neurotransmitter receptors, making it valuable in medicinal chemistry for optimizing drug candidates. Also employed in the development of receptor ligands for studying dopamine and serotonin systems.
