Used as a key intermediate in the synthesis of fluorescent dyes and contrast agents, particularly in medical imaging. Its structure allows for easy functionalization, making it valuable in developing X-ray contrast media due to the presence of iodine atoms, which provide high radiopacity. Also employed in the preparation of ligands for metal-catalyzed reactions and in the fabrication of organic semiconductors. Its diamine groups enable polymerization or chelation processes useful in material science and pharmaceutical research.
