Used as a chiral resolving agent in the separation of enantiomers, particularly in pharmaceutical synthesis. It helps in the purification of optically active compounds by forming diastereomeric salts. Commonly applied in the production of enantiomerically pure drugs, ensuring high specificity and efficacy. Also utilized in asymmetric synthesis and catalysis to achieve desired stereochemical outcomes in organic reactions. Its role in fine chemical manufacturing makes it valuable for producing intermediates with precise chiral configurations.
