Used as a key intermediate in the synthesis of pharmaceutical compounds, particularly in the development of central nervous system (CNS) agents. It is commonly employed in the production of antidepressants and antipsychotic drugs due to its ability to modulate neurotransmitter activity. The compound’s lipophilic nature, enhanced by the trifluoromethyl group, improves blood-brain barrier penetration, making it valuable in neuroactive drug design. It also finds use in medicinal chemistry research for structure-activity relationship (SAR) studies involving pyrrolidine-based analogs.
