Chloranilic acid (CAT: R052035) is a halogenated quinonoid compound featuring two hydroxyl and two chlorine substituents on a benzoquinone core. Known for its strong electron-accepting properties, chloranilic acid is widely used in coordination chemistry, charge-transfer complex studies, and as a redox-active ligand. It readily forms stable metal-organic complexes, making it valuable for investigating electron transfer processes and supramolecular assembly. Its conjugated structure and redox behavior also support applications in electrochemical research and organic electronics.
