Used as a key chiral intermediate in the synthesis of pharmaceutical agents, particularly in the development of antidepressants and antiviral drugs. Its stereochemistry enables selective interactions with biological targets, enhancing drug efficacy and reducing side effects. Commonly employed in medicinal chemistry for structure-activity relationship studies due to the stability and bioavailability imparted by the trifluoromethyl group. Also utilized in the preparation of pyrrolidine-based catalysts for asymmetric synthesis.
