Used as a key chiral intermediate in the synthesis of biologically active compounds, particularly in pharmaceuticals targeting central nervous system disorders. Its structure supports the development of selective enzyme inhibitors and receptor modulators. The presence of the trifluoromethyl group enhances metabolic stability and lipophilicity, making it valuable in optimizing drug candidates for improved bioavailability and potency. Commonly employed in the preparation of serotonin and dopamine receptor ligands, it plays a role in the development of antidepressants and antipsychotic agents.
