Used as a chiral modifier in heterogeneous catalysis, particularly in the enantioselective hydrogenation of α-keto esters and similar prochiral compounds. It plays a key role in asymmetric synthesis, enabling the production of optically active intermediates for pharmaceuticals. Commonly applied in the modification of platinum or palladium catalysts to achieve high enantiomeric excess in reactions such as the hydrogenation of pyruvates to form lactates. Also utilized in studies of chiral recognition and surface adsorption behavior due to its ability to impart stereoselectivity in catalytic systems.
