5-Chloro-2-hydroxybenzophenone
5-Chloro-2-hydroxybenzophenone (CAS: 85-19-8), with the molecular formula ClC6H3(OH)COC6H5 and a molecular weight of 232.66 g/mol, is a benzophenone derivative. It is primarily utilised as a UV absorber and light stabilizer in various polymer applications, offering protection against photodegradation. This compound plays a crucial role in enhancing the durability and longevity of polymeric materials exposed to sunlight.
UV Absorber in Polymers
5-Chloro-2-hydroxybenzophenone functions as an effective UV absorber, dissipating harmful ultraviolet radiation as heat. This protects polymers from degradation, preventing yellowing, cracking, and loss of mechanical properties.
Light Stabilizer
As a light stabilizer, it helps to extend the service life of plastics and coatings by preventing photo-oxidative decomposition. It is incorporated into formulations to maintain aesthetic and structural integrity under light exposure.
Intermediate in Chemical Synthesis
The compound can serve as a building block in the synthesis of more complex organic molecules. Its functional groups allow for further chemical modifications in the development of specialized chemicals and materials.
