Trisodium aminotris(methylenephosphonate)

Trisodium aminotris(methylenephosphonate) (CAS 7611-50-9 ), the trisodium salt form of ATMP, is a phosphonate chelating agent used across water treatment and industrial cleaning applications. It controls scale deposition and inhibits corrosion by sequestering calcium, magnesium, and heavy metal ions in aqueous systems. In industrial water treatment, it is dosed into cooling water circuits. It is also used in boiler systems to prevent calcium carbonate and calcium sulfate scale buildup on heat exchange surfaces. Cleaning and detergent formulators incorporate it to sequester hardness ions. This improves surfactant performance and prevents redeposition of soil in industrial and institutional formulations. In textile processing, it stabilizes peroxide bleach baths by chelating trace metal ions. These ions would otherwise catalyze premature decomposition. Paper and leather processing operations use it to control metal ion interference during bleaching and tanning stages. Trisodium aminotris(methylenephosphonate) is supplied as an aqueous solution, with concentration typically around 40–50% active content. Technical grade is the standard commercial specification. This specification is ideal for water treatment and industrial applications. Packaging options commonly include drums and IBC totes suited to bulk industrial procurement needs.
