Used as a chiral building block in the synthesis of pharmaceuticals, particularly in the development of fluorinated active pharmaceutical ingredients (APIs) where the (R)-enantiomer provides desired biological activity. Its trifluorinated aryl amine structure enhances metabolic stability and membrane permeability, making it valuable in central nervous system (CNS) agents and kinase inhibitors. Commonly employed in asymmetric synthesis and catalysis to introduce chirality in drug candidates. Also utilized in agrochemicals for creating enantiomerically pure herbicides and pesticides with improved environmental profiles.
