General description

2-Phenyl-5-benzimidazolesulfonic acid has been reported as UV filter. It is a xenobiotic compound detected in in gray water from houses and effluents of the biological treatment systems (aerobic, anaerobic, and combined anaerobic+aerobic). It is a micropollutant of personal care products and its removal from aerobically treated grey water by ozonation and adsorption onto activated carbon has been reported.

Application

2-Phenyl-5-benzimidazolesulfonic acid was used for the fabrication of biomimetic sensor for determination of 4-methylbenzylidene camphor (4-MBC), an ultraviolet (UV) radiation protector.
