Used as a chiral resolving agent in organic synthesis, particularly for the separation of enantiomers of basic compounds such as amines and amino alcohols. Its effectiveness stems from the formation of diastereomeric salts with racemic mixtures, where differences in solubility allow for selective crystallization. Commonly employed in the pharmaceutical industry to obtain enantiomerically pure intermediates. Also utilized in asymmetric synthesis and chiral pool strategies due to its rigid structure and strong hydrogen-bonding capability.
