Benzophenone is a naturally occurring organic compound with the formula (C₆H₅)₂CO, generally abbreviated Ph₂CO. Benzophenone has been found in some fungi, fruits and plants, including grapes. It is a white solid with a low melting point and rose-like odor that is soluble in organic solvents. Benzophenone is the simplest diaromatic ketone. It is a widely used building block in organic chemistry, being the parent diarylketone.
