Used as a chiral derivatizing agent in organic synthesis, particularly for the resolution of racemic mixtures of alcohols and amines. It selectively reacts with enantiomers to form diastereomeric esters or amides, which can be separated by conventional methods such as crystallization or chromatography. After separation, the desired enantiomer can be recovered by hydrolysis. Commonly employed in the pharmaceutical industry to obtain enantiomerically pure intermediates. Also used in asymmetric synthesis and stereochemical analysis due to its ability to induce and maintain chirality.
