Used as a chiral phase-transfer catalyst in asymmetric synthesis, particularly in the enantioselective alkylation of glycine derivatives to produce optically active amino acids. It facilitates the formation of chiral centers with high enantiomeric excess, making it valuable in the synthesis of pharmaceuticals and fine chemicals. Additionally, it is employed in the preparation of intermediates for drugs and agrochemicals, where precise stereochemistry is critical for biological activity. Its trifluoromethyl group enhances its catalytic efficiency and stability under various reaction conditions.
