Pentasodium aminotrimethylene phosphonate

Pentasodium aminotrimethylene phosphonate (CAS 2235-43-0 ) is the pentasodium salt form of ATMP, a phosphonate chelating agent used to control scale formation and metal ion interference. Its ability to sequester calcium, magnesium, and heavy metal ions makes it a standard input in water treatment chemistry and process fluid formulation for various industrial systems. In cooling water and boiler systems, it inhibits calcium carbonate and calcium sulfate scale deposition, protecting heat exchange surfaces and extending equipment service life effectively. Textile and paper processing operations use it to sequester hardness ions in process water, preventing interference with dyes, bleaches, and sizing agents during the manufacturing cycle. In oilfield applications, it functions as a scale inhibitor in injection water and produced water treatment, where mineral scaling in pipelines and wellbores is a persistent problem. Mining and metals processing operations apply it in leaching circuits and metal surface treatment baths to stabilize metal ion concentrations and reduce corrosion on process equipment. The product is supplied as a clear to pale yellow aqueous solution, typically at 40–50% active content. Technical grade is the standard commercial specification for these applications. Bulk liquid supply in IBC containers and tanker quantities is the norm for high-volume industrial procurement, ensuring consistent availability for large-scale water treatment facilities.
