2,2-Dihydroxy-4,4-dimethoxybenzophenone丨CAS 131-54-4

2,2-Dihydroxy-4,4-dimethoxybenzophenone is widely used as a photoinitiator and UV absorber in polymer, coating, and cosmetic industries. It is commonly incorporated into plastics, coatings, varnishes, and adhesives to protect materials from UV-induced degradation, discoloration, and loss of mechanical properties. The compound is also employed in sunscreen formulations, personal care products, and cosmetic applications due to its ability to absorb and dissipate harmful ultraviolet light. Additionally, it serves as an intermediate in organic synthesis and materials research, where its hydroxyl and methoxy groups allow for further functionalization and the development of UV-stable derivatives.

The benefits of 2,2-Dihydroxy-4,4-dimethoxybenzophenone include its strong UV absorption, chemical stability, and compatibility with a wide range of polymers and formulations. Its hydroxyl groups enable hydrogen bonding and incorporation into polymer matrices, improving photostability and resistance to thermal or oxidative degradation. The methoxy substituents enhance solubility in organic solvents and facilitate formulation into coatings, plastics, or cosmetic products. Its stability under standard storage and processing conditions ensures long-term effectiveness, making it a reliable additive for protecting materials and formulations from UV damage.
