2-(2H-benzotriazol-2-yl)-4-tert-butylphenol

Description:
2-(2H-benzotriazol-2-yl)-4-tert-butylphenol, commonly known as UV-328, is an organic compound characterized by its structure that includes a benzotriazole moiety and a tert-butyl group attached to a phenolic ring. This compound is primarily used as a UV stabilizer in various polymers, enhancing their resistance to photodegradation. It exhibits excellent thermal stability and solubility in organic solvents, making it suitable for applications in plastics, coatings, and adhesives. The presence of the benzotriazole group contributes to its ability to absorb UV radiation, thereby protecting materials from the harmful effects of sunlight. Additionally, UV-328 is known for its low volatility and high molecular weight, which contribute to its effectiveness as a long-lasting stabilizer. However, environmental and health concerns have been raised regarding its persistence and potential toxicity, leading to increased scrutiny and regulation in some regions. Overall, UV-328 plays a significant role in extending the lifespan of materials exposed to UV light, although its use is being carefully evaluated in light of environmental safety.
