Usage

Uses

Used in Plastics Industry:
2-(2'-Hydroxy-3'-sec-butyl-5'-tert-butylphenyl)benzotriazole is used as a UV stabilizer for plastics to increase product stability and prevent discoloration. Its ability to absorb UV radiation helps protect plastics from degradation caused by exposure to sunlight or other UV sources, thereby extending their lifespan and maintaining their appearance.
Used in Aquatic Environment:
Although 2-(2'-Hydroxy-3'-sec-butyl-5'-tert-butylphenyl)benzotriazole is a pollutant for the aquatic environment, it has been implicated as a potential stable and toxic ligand for the aryl hydrocarbon receptor in humans. This suggests that further research is needed to understand its impact on both the environment and human health.
