Used as a chiral resolving agent in the separation of enantiomers, particularly in the pharmaceutical industry to produce optically pure compounds. It is effective in forming diastereomeric salts with racemic mixtures, allowing for the isolation of specific enantiomers. Commonly applied in the synthesis of chiral drugs, agrochemicals, and fine chemicals. Also utilized in asymmetric synthesis and catalysis to enhance stereoselectivity in chemical reactions. Its stability and efficiency make it a preferred choice in enantiomeric resolution processes.
