Used as a corrosion inhibitor in industrial water treatment systems, particularly in cooling circuits where it prevents scale formation and protects metal surfaces. Exhibits good chelating properties for multivalent metal ions, making it effective in detergent formulations and cleaning products to enhance performance under hard water conditions. Also employed in oilfield applications to control calcium carbonate and sulfate scale in pipelines and downhole equipment. Shows thermal stability and remains effective over a wide pH range, which supports its use in both low- and high-temperature processes.
