Used as a chiral resolving agent in organic synthesis, particularly for the separation of enantiomers of carboxylic acids and other acidic compounds. Its effectiveness stems from its ability to form diastereomeric salts with racemic mixtures, which differ in solubility and can be separated by crystallization. Commonly applied in the pharmaceutical industry to obtain enantiomerically pure intermediates. Also employed in asymmetric synthesis and chiral pool strategies where stereochemistry control is critical. Suitable for use in research settings for studying chiral recognition and enantioselective reactions.
