dibenzoylmethane

Dibenzoylmethane is an organic compound with the chemical formula C15H12O2. It is a diketone, meaning it contains two ketone functional groups. Specifically, it is a beta-diketone, where the two carbonyl groups are separated by a single methylene group. It can exist in tautomeric forms, with the enol form being particularly stable due to intramolecular hydrogen bonding and conjugation.

This compound is often synthesized through a Claisen condensation reaction between ethyl benzoate and acetophenone. It is a solid at room temperature and is soluble in many organic solvents. Dibenzoylmethane has found applications as a chelating agent, forming complexes with various metal ions. Its ability to absorb ultraviolet (UV) radiation has also led to its use as a UV stabilizer in plastics and cosmetics, protecting materials from photodegradation and providing sun protection. It has also been investigated for its potential biological activities, including antioxidant and anti-inflammatory properties, although further research is ongoing in these areas.
