/qui·none/ (kwi´nōn) (kwin´ōn) any of a group of highly aromatic compounds derived from benzene or from multiple ring hydrocarbons and containing two ketone group substitutions; they are subclassified on the basis of ring structure (i.e., anthraquinone, benzoquinone) and are mild oxidizing agents. Often used specifically to denote benzoquinone, particularly 1,4-benzoquinone.
