Used as a key intermediate in the synthesis of biologically active compounds, particularly in pharmaceuticals targeting central nervous system disorders. Its structure supports the development of dopamine and serotonin receptor modulators. Commonly employed in medicinal chemistry for optimizing drug candidates due to the presence of trifluoromethyl and pyrrolidine groups, which enhance metabolic stability and blood-brain barrier penetration. Also utilized in the preparation of analogs for structure-activity relationship studies.
