Used in chiral resolution to separate enantiomers of basic organic compounds, particularly in the pharmaceutical industry. It forms diastereomeric salts with racemic mixtures of chiral amines, allowing for the isolation of optically active components due to differences in solubility. Commonly employed in the purification of intermediates for drug synthesis. Also utilized as a chiral derivatizing agent in analytical chemistry to determine enantiomeric purity. Its crystalline structure aids in efficient filtration and recovery during industrial processes.
