Used as a chiral derivatizing agent in enantioselective analysis, particularly in high-performance liquid chromatography (HPLC) to resolve racemic mixtures of amines and amino acids. Its rigid anthracene core and defined stereochemistry enable strong chromophoric detection and efficient chiral recognition. Also employed in asymmetric synthesis as a chiral auxiliary due to its ability to direct stereoselective transformations. The carboxylic acid and imide functional groups allow for easy conjugation and further chemical modification, making it valuable in the design of stereoselective sensors and catalysts.
