Used as a chiral derivatizing agent in the resolution of racemic mixtures, particularly in the pharmaceutical industry for the separation of enantiomers. Its ester groups react selectively with chiral alcohols or amines, enabling the formation of diastereomers that can be separated by conventional techniques such as crystallization or chromatography. Employed in analytical chemistry to determine enantiomeric purity and to assist in the stereochemical analysis of bioactive molecules. Also finds use in asymmetric synthesis as a building block for complex organic molecules where stereocontrol is critical.
