Used as a corrosion inhibitor in industrial water treatment systems, particularly in cooling water circuits. Effective in protecting mild steel and copper alloys from corrosion under varying pH and temperature conditions. Commonly applied in combination with other treatment chemicals to enhance performance in closed-loop systems. Also utilized in oil and gas production systems to prevent metal degradation in pipelines and downhole equipment exposed to sour environments. Shows good compatibility with scale inhibitors and biocides, making it suitable for comprehensive water treatment programs.
