flavone
Sign in to saveAlso known as 2-Phenylbenzopyran-4-one, 2-Phenyl-4-chromone, 2-Phenyl-4-benzopyron, 2-phenylchromen-4-one, 2-phenyl-1-benzopyran-4-one, 2-phenyl-γ-benzopyrone, 2-phenyl-4H-benzopyran-4-one
Flavone is an organic compound with the formula . A white solid, flavone is a derivative of chromone with a phenyl (Ph) substituent adjacent to the ether group. The compound is of little direct practical importance, but substituted derivatives, the flavones and flavonoids are a large class of nutritionally important natural products. Flavone can be prepared in the laboratory by cyclization of 2-hydroxacetophenone. Isomeric with flavone is isoflavone, where the phenyl group is adjacent to the ketone.
