Used as a chiral building block in the synthesis of pharmaceuticals, particularly in the development of central nervous system agents and antidepressants. Its trifluoromethyl-substituted aryl group enhances metabolic stability and lipophilicity, making it valuable in drug design. Commonly employed in asymmetric synthesis and as an intermediate in the preparation of bioactive molecules, including those targeting neurological disorders. Also utilized in agrochemicals for the creation of enantiomerically pure active ingredients.
