2-sec-Butyl-4-tert-butylphenol is an intermediate in the synthesis of 2-(2H-Benzotriazol-2-yl)-4-(tert-butyl)-6-(sec-butyl)phenol (B206645), which is often used to increase product stability and to prevent discolouration in various consumer and industrial goods such as plastics. Benzotriazole UV stabilizers, such as 2-(2H-Benzotriazol-2-yl)-4-(tert-butyl)-6-(sec-butyl)pheno, are pollutants for the aquatic environment and have been implicated as a potential stable and toxic ligands for the aryl hydrocarbon receptor in human.
