Used as a chiral derivatizing agent in stereochemical analysis, particularly in the determination of enantiomeric purity of chiral alcohols and amines. Its rigid structure and two ester functionalities allow it to form diastereomeric esters with enantiomers, which can then be separated and analyzed using techniques like HPLC or NMR. The presence of aromatic groups enhances detectability by UV detection. Commonly applied in pharmaceutical research for resolving racemic mixtures and validating asymmetric synthesis pathways.
