2-(2H-Benzotriazol-2-yl)-4,6-di-tert-pentylphenol (CAS 25973-55-1) is an ultraviolet (UV) stabilizer with a phenolic group connected to the benzotriazole structure. These phenolic groups facilitate the absorption of UV light. UV-328 is mainly used in as a light stabilizer for coating and as an additive for industrial polymers. It is a class of benzotriazole derivatives that can potentially be used as corrosion inhibitors in heat resistant fluids in aircraft, brake fluids in automobiles and for other industrial cooling systems.
