Used as a chiral resolving agent in organic chemistry, particularly for the separation of enantiomers of acidic compounds such as tartaric acid and other racemic carboxylic acids. Its stereoselective properties make it valuable in the pharmaceutical industry for purifying enantiomerically pure intermediates. Also employed as a catalyst or modifier in asymmetric synthesis, contributing to the production of optically active drugs. Additionally, it finds use in analytical chemistry for chiral derivatization in HPLC and capillary electrophoresis to enable enantiomer differentiation.
