Used as a chiral resolving agent in organic synthesis, particularly for the separation of enantiomers of carboxylic acids and other acidic compounds. Its ability to form diastereomeric salts with racemic mixtures allows for effective resolution through crystallization. Commonly employed in the pharmaceutical industry to obtain enantiomerically pure intermediates. Also utilized in asymmetric synthesis and chiral pool strategies where stereochemical control is critical. Suitable for laboratory-scale resolutions and in the development of chiral stationary phases for chromatography.
