Used as a chiral solvent in asymmetric synthesis, enabling stereoselective reactions in pharmaceutical manufacturing. Commonly employed in the production of enantiomerically pure drugs, especially in the synthesis of active pharmaceutical ingredients (APIs) where optical purity is critical. Also serves as an intermediate in the preparation of chiral ligands and catalysts. Its ability to dissolve a wide range of organic compounds while maintaining stereochemical integrity makes it valuable in fine chemical and agrochemical industries. Additionally, it functions as a resolving agent for racemic mixtures and is utilized in analytical applications such as chiral chromatography.
