Used as a chiral building block in the synthesis of pharmaceuticals, particularly in the development of fluorinated active pharmaceutical ingredients (APIs). Its trifluorinated aryl group enhances metabolic stability and membrane permeability, making it valuable in optimizing drug candidates for central nervous system (CNS) disorders. Commonly employed in asymmetric synthesis to introduce stereochemistry in protease inhibitors and receptor modulators. Also utilized in agrochemicals for creating enantiomerically pure herbicides and fungicides with improved environmental profiles.
