Used as a chiral catalyst in asymmetric synthesis, particularly in enantioselective reductions and transformations where high stereocontrol is required. Its borate structure stabilizes reactive intermediates and enhances selectivity in carbon–carbon bond-forming reactions. Commonly applied in pharmaceutical synthesis to produce single-enantiomer compounds, especially in the development of bioactive molecules with defined stereochemistry. Also employed in organocatalytic cycles due to its thermal stability and solubility in polar organic solvents.
