Used as a chiral resolving agent in the separation of enantiomers, particularly in the pharmaceutical industry for purifying racemic mixtures. Its chiral amine structure allows it to form diastereomeric salts with acidic compounds, enabling effective crystallization-based separation. Commonly applied in the production of single-enantiomer drugs where stereochemistry impacts biological activity. Also employed as a building block in asymmetric synthesis and as a catalyst precursor in certain organic transformations.
