Request SDS →Pentasodium Aminotrimethylene Phosphonate (CAS 2235-43-0) is the pentasodium salt of aminotris(methylenephosphonic acid), supplied as an aqueous phosphonate. It is used as a scale and corrosion inhibitor in cooling and boiler water treatment, as a chelating and dispersing agent, and as a stabilizer for peroxide bleaching solutions in textile and paper processing.
Frequently Asked Questions
What is ATMP.Na5 (pentasodium aminotrimethylene phosphonate) used for?
Pentasodium aminotrimethylene phosphonate (CAS 2235-43-0) is the pentasodium salt of aminotris(methylenephosphonic acid), supplied as an aqueous phosphonate. It is used as a scale and corrosion inhibitor in cooling and boiler water, as a chelating/dispersing agent, and as a stabilizer for peroxide bleaching in textile and paper processing.
How does ATMP.Na5 inhibit scale?
It works as a chelant and threshold inhibitor, sequestering calcium, magnesium, and transition-metal ions and disrupting crystal growth so that scale-forming salts stay dispersed rather than depositing. This makes it effective in cooling and boiler water-treatment programs at sub-stoichiometric doses.
What is the difference between ATMP and ATMP.Na5?
ATMP is the free aminotris(methylenephosphonic acid); ATMP.Na5 is its pentasodium salt, fully neutralized to a near-neutral pH and supplied as an aqueous solution. The sodium salt form is preferred where a low-acidity, ready-to-dose liquid is wanted.
What is the CAS number and HS code for ATMP.Na5?
It carries CAS 2235-43-0 and the molecular formula C3H7NNa5O9P3, and typically classifies under HS heading 2931.49 (organo-phosphorus compounds). Confirm the import classification for your jurisdiction with your broker.
How is bulk ATMP.Na5 supplied, and how do I get a price?
RawSource supplies this aqueous phosphonate in bulk industrial packaging such as drums and IBCs/totes for water-treatment and process users. Pricing depends on volume and active concentration; request a bulk quote with quantity and ship-to and we will include current CoA and SDS.
