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 ability to form diastereomeric salts with racemic mixtures allows for the isolation of optically pure enantiomers through selective crystallization. Commonly applied in the pharmaceutical industry for the purification of chiral intermediates. Also employed in asymmetric synthesis and chiral pool strategies where high enantiomeric excess is required. Its derivatized structure enhances solubility and crystallinity, making it favorable for practical resolutions.
