A quinone is a class of organic compounds that are formally "derived from aromatic compounds [such as benzene or naphthalene] by conversion of an even number of –CH= groups into –C(=O)– groups with any necessary rearrangement of double bonds," resulting in "a fully conjugated cyclic dione structure." The class includes some heterocyclic compounds.
