Used as a chiral resolving agent in the separation of enantiomers in organic synthesis. It is particularly effective in forming diastereomeric salts with racemic mixtures, allowing for the purification of optically active compounds. Commonly applied in pharmaceutical research to isolate specific enantiomers of drugs, ensuring higher efficacy and reduced side effects. Also utilized in the development of chiral stationary phases for high-performance liquid chromatography (HPLC), enhancing the analysis and separation of chiral molecules in complex mixtures.
