Used as a corrosion inhibitor in industrial water treatment systems, particularly in cooling water circuits. Effective in protecting carbon steel and copper alloys from oxidative degradation under neutral to alkaline pH conditions. Commonly applied in combination with azoles and phosphate-based treatments to enhance film formation on metal surfaces. Also utilized in closed-loop heating systems to prevent pitting and scale buildup. Shows good compatibility with biocides and dispersants, making it suitable for integrated water treatment programs.
