The invisible threat of ultraviolet (UV) radiation poses a significant challenge across various industries, from protecting delicate skin in cosmetics to preventing degradation in advanced materials. The effectiveness of UV protection hinges on specialized chemical compounds known as UV absorbers. Among these, 4-Hydroxybenzophenone (CAS 1137-42-4) stands out for its robust performance, rooted in its unique chemical structure and absorption capabilities.

Understanding the chemistry behind UV absorption is key to appreciating the value of compounds like 4-Hydroxybenzophenone. This molecule belongs to the benzophenone class, characterized by a diphenyl ketone structure. The presence of the hydroxyl (-OH) group in the para position of one of the phenyl rings significantly influences its electronic properties, particularly its ability to absorb UV radiation. When UV photons strike the molecule, they excite electrons to higher energy levels. The molecule then rapidly returns to its ground state, dissipating the absorbed energy as heat, effectively neutralizing the harmful UV radiation.

This photophysical process makes 4-Hydroxybenzophenone an excellent choice for applications requiring long-term UV stability. In the cosmetic industry, it's a vital component in sunscreens and anti-aging products, absorbing both UVA and UVB rays to shield the skin from sunburn and premature aging. For material scientists, its incorporation into plastics, coatings, and textiles prevents yellowing, cracking, and loss of strength when exposed to sunlight. For those looking to buy 4-Hydroxybenzophenone for these critical applications, quality is paramount.

As a leading manufacturer in China, we ensure that our 4-Hydroxybenzophenone consistently meets high purity standards (≥99%). This guarantees its efficacy as a UV absorber and its reliability as a pharmaceutical intermediate for complex organic synthesis.
