Tolyltriazole

Tolyltriazole (CAS 29385-43-1), also known as methylbenzotriazole or TTZ, is a heterocyclic corrosion inhibitor.

Where is Tolyltriazole used?

• Lubricant and metalworking fluids: metal deactivator protecting copper-containing components during machining and high-load operations
• Automotive coolants: safeguards brass and copper radiator components
• Water treatment: controls copper corrosion in cooling tower and closed-loop systems under varying pH and temperature
• Industrial and institutional cleaning: tarnish inhibitor maintaining metal surfaces after contact with aggressive cleaning agents
• It forms a stable protective complex on copper and copper alloy surfaces, preventing oxidative and electrochemical degradation.

Commercial specifications

• Purity typically 98% or higher
• Packaging from small drums to bulk quantities
