CAS 25973-55-1: UV 328

Description: UV 328, also known by its chemical name 2-(2H-benzotriazol-2-yl)-4-(tert-butyl)-6-(1,1-dimethyl-ethyl)phenol, is a widely used ultraviolet (UV) light stabilizer. It belongs to the class of benzotriazole derivatives and is primarily employed to protect polymers, coatings, and other materials from UV radiation degradation. UV 328 exhibits excellent thermal stability and high absorptive capacity for UV light, effectively preventing photodegradation and maintaining the integrity of materials exposed to sunlight. This compound is characterized by its ability to absorb UV light in the range of 290 to 400 nm, making it particularly effective in outdoor applications. Additionally, UV 328 is known for its low volatility and compatibility with various polymers, enhancing its utility in diverse formulations. However, there are environmental and health concerns associated with its use, as it may persist in the environment and has been scrutinized for potential endocrine-disrupting effects. Therefore, its application is subject to regulatory considerations in many regions.
