Description
High-Quality Tolytriazole
Tolytriazole (TTA), chemically designated as 4-methyl-1H-benzotriazole with CAS number 29385-43-1, molecular formula C₇H₇N₃, and molecular weight 133.15 g/mol, is a white crystalline powder or granular material that represents one of the most effective corrosion inhibitors for copper and copper alloy components. This advanced benzotriazole derivative is produced as a mixture of isomers, primarily 4-methyl-benzotriazole and 5-methyl-benzotriazole, providing enhanced corrosion protection through formation of protective thin films on metal surfaces. With melting point range 80-84°C and excellent solubility characteristics in both aqueous and organic systems, tolytriazole demonstrates outstanding thermal stability up to 200°C, exceptional oxidative stability, and remarkable UV light resistance properties. The compound functions by adsorbing onto copper surfaces to form uniform protective membranes that effectively shield copper and copper alloys from corrosion caused by atmospheric conditions, water exposure, and various chemical environments, making it essential for power plant cooling systems, industrial water treatment, metalworking operations, automotive applications, and specialized industrial processes requiring reliable metal protection and proven long-term performance.
