Used as a corrosion inhibitor in industrial water treatment systems, particularly in cooling water and boiler systems. It protects metal surfaces, especially copper and its alloys, by forming a protective film that prevents oxidation and degradation caused by water and dissolved oxygen. Also employed in the oil and gas industry to safeguard pipelines and equipment from sulfide stress cracking. Its effectiveness in acidic and high-temperature environments makes it suitable for use in acidizing treatments in oil wells. Additionally, it serves as an additive in metalworking fluids to enhance lubricant performance and extend tool life.
