Tetrachlorocatechol

Tetrachlorocatechol is an organochlorine compound with the formula C6Cl4(OH)2. It is a white solid. It results from the degradation of the controversial pesticide pentachlorophenol.[2] It is a precursor to the reagent TRISPHAT. Its conjugate base also functions as a ligand for transition metals.[3]
