Template:Chembox Footer/trackingTemplate:Short description

Flavone is an organic compound with the formula Page Module:Chem2/styles.css has no content.C6H4OC3H(Ph)O. 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.[2] Flavone can be prepared in the laboratory by cyclization of 2-hydroxacetophenone.[3] Isomeric with flavone is isoflavone, where the phenyl group is adjacent to the ketone.
