Used as a corrosion inhibitor in industrial water treatment systems, particularly in cooling water and boiler applications. It helps prevent metal degradation by forming a protective film on metal surfaces, reducing oxidation and extending equipment lifespan. Commonly applied in oil refineries, power plants, and chemical processing facilities where water circulates at high temperatures and pressures. Effective in low concentrations and compatible with other treatment chemicals like biocides and scale inhibitors. Also utilized in closed-loop systems to protect carbon steel, copper, and aluminum alloys from pitting and general corrosion.
