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 modulation of neurotransmitter receptors, making it valuable in the design of antidepressants, antipsychotics, and anxiolytic drugs. The presence of the trifluoromethyl group enhances metabolic stability and lipophilicity, improving blood-brain barrier penetration. Also employed in medicinal chemistry research to explore structure-activity relationships in piperidine-based bioactive molecules.
