Used as a chiral derivatizing agent in the resolution of racemic mixtures, particularly for the separation of enantiomers of chiral alcohols and amines. Its ability to form diastereomeric esters or amides with different physical properties allows for effective separation by crystallization or chromatography. Commonly employed in asymmetric synthesis and pharmaceutical research where enantiomeric purity is critical. Also utilized in the preparation of optically active compounds, including intermediates for drug synthesis, due to its stability and well-defined stereochemistry.
