Used as a corrosion inhibitor in industrial water treatment systems, particularly in cooling water circuits and boiler systems. It helps prevent metal degradation by forming a protective layer on metal surfaces, reducing oxidation and extending equipment lifespan. Commonly applied in power plants, refineries, and HVAC systems where metal integrity is critical. Also utilized in antifreeze formulations to protect aluminum and ferrous components. Effective at low concentrations and compatible with various water chemistries.
