Used as a corrosion inhibitor in industrial water treatment systems, particularly in cooling water circuits. Provides effective protection for ferrous metals by forming a thin, protective film on metal surfaces. Compatible with various water chemistries and often used in combination with other treatment chemicals to enhance performance. Suitable for use in low to medium pressure boiler systems and closed-loop heating systems to prevent rust and scale buildup. Also applied in oil and gas production systems to protect pipelines and downhole equipment from acidic corrosion.
