Used as a chiral derivatizing agent in the resolution of racemic mixtures, particularly for the separation of enantiomers in pharmaceutical compounds. Its structure allows for selective binding to specific enantiomeric forms, making it valuable in high-performance liquid chromatography (HPLC) and capillary electrophoresis. It is also employed in asymmetric synthesis to control stereochemistry in complex organic molecules, especially in the development of active pharmaceutical ingredients where chirality affects biological activity.
