Used as a chiral selector in capillary electrophoresis for enantiomeric separation of pharmaceuticals and biological compounds. Its tetraacetic acid structure enables strong complexation with metal ions, making it effective in chiral coordination environments. Also applied in asymmetric synthesis and as a ligand in catalytic systems where stereochemical control is required. Shows utility in analytical chemistry for resolving racemic mixtures due to its ability to form diastereomeric complexes with enantiomers.
