Used as a chiral resolving agent in the separation of enantiomers, particularly in the resolution of racemic mixtures of carboxylic acids and amines. Its structural features allow it to form diastereomeric salts with chiral acids or bases, which can be separated based on differences in solubility or crystallization behavior. Commonly applied in asymmetric synthesis and pharmaceutical intermediate purification where enantiomeric purity is critical. Also employed in the development of chiral stationary phases for chromatography due to its ability to discriminate between enantiomers.
