Used as a chiral organocatalyst in asymmetric synthesis, particularly in enantioselective fluorination and trifluoromethylation reactions. Its rigid, fluorinated structure enhances stereocontrol and stability under reactive conditions, making it effective for constructing chiral centers in pharmaceutical intermediates. Commonly applied in the development of bioactive molecules where high enantiomeric excess is required. The tetrafluoroborate counterion supports solubility in polar aprotic solvents, facilitating its use in homogeneous catalysis.
