Used as a key intermediate in the synthesis of pharmaceutical agents, particularly in the development of selective receptor modulators. Its structure supports the design of bioactive molecules with improved binding affinity and metabolic stability. Commonly employed in research for central nervous system drugs due to the presence of the piperazine ring and trifluoromethyl group, which enhance blood-brain barrier penetration and pharmacokinetic properties. Also utilized in the preparation of analogs for structure-activity relationship studies in medicinal chemistry.
