Used as a chiral intermediate in the synthesis of pharmaceuticals, particularly in the development of central nervous system (CNS) agents and antidepressants. Its trifluoromethyl and bromo-substituted aryl groups enhance binding selectivity and metabolic stability in drug candidates. Commonly employed in asymmetric synthesis to introduce stereochemical control in active pharmaceutical ingredients (APIs). Also utilized in the preparation of fluorinated analogs for structure-activity relationship (SAR) studies.
