2,4-Dihydroxybenzophenone（Cat No.:R015596）is an aromatic ketone compound featuring two hydroxyl groups at the 2- and 4-positions of one phenyl ring and a benzoyl group at the para position. It is widely used as a UV absorber and photostabilizer in plastics, coatings, cosmetics, and sunscreens to protect materials and formulations from UV-induced degradation. The hydroxyl groups enhance its ability to absorb harmful UV radiation, particularly in the UVA and UVB range. It typically appears as a pale yellow crystalline solid, soluble in organic solvents, and stable under normal storage conditions.
