Used as a chiral building block in the synthesis of pharmaceuticals, particularly in the development of central nervous system agents. Its trifluoromethyl group enhances metabolic stability and lipophilicity, making it valuable in drug design for improving bioavailability and blood-brain barrier penetration. Commonly employed in asymmetric synthesis to introduce chirality in active pharmaceutical ingredients. Also utilized in agrochemicals for creating enantiomerically pure herbicides and insecticides.
