Used as a key intermediate in the synthesis of pharmaceutical compounds, particularly in the development of active pharmaceutical ingredients (APIs) with central nervous system activity. It serves in the production of selective receptor modulators, including serotonin and dopamine receptor ligands, which are relevant in treating psychiatric and neurological disorders. Its cyclopropyl and piperazine moieties enhance metabolic stability and binding affinity in drug candidates. Also employed in the preparation of antimicrobial agents and kinase inhibitors in medicinal chemistry research.
