Amino Trimethylene Phosphonic Acid (ATMP)
ATMP
CAS 6419-19-8 ·Formula C3H12NO9P3 ·MW 299.05 g/mol
An organophosphonate scale-and-corrosion inhibitor and chelant for industrial water systems. It is used mainly as a chelating/sequestering and deflocculant agent and as a scale and corrosion inhibitor in industrial water treatment, and as a stabilizer for peroxide bleaching solutions in textile and paper processing.
A grade-specific Safety Data Sheet (SDS) — with the complete hazard classification, handling precautions, and transport information — is supplied with every shipment and available on request. Confirm all safety and regulatory details against the SDS for your specific grade.
Transport classification per the UN Model Regulations / 49 CFR 172.101 Hazardous Materials Table. Confirm against the grade-specific SDS (Section 14) before shipping.

Frequently Asked Questions
What is the use of ATMP chemical?
Amino trimethylene phosphonic acid (ATMP, CAS 6419-19-8) is an organophosphonate used mainly as a scale and corrosion inhibitor in industrial water treatment. It also functions as a chelating/sequestering agent and deflocculant and as a stabilizer for peroxide bleaching solutions.
What chemical is ATMP?
ATMP is amino trimethylene phosphonic acid, formula C3H12NO9P3 (CAS 6419-19-8), a nitrogen-centered organophosphonate sequestrant. The full name is amino trimethylene phosphonic acid.
How does ATMP prevent scale in water systems?
ATMP sequesters calcium, magnesium, and other metal ions and disrupts crystal growth at sub-stoichiometric (threshold) dosages, keeping hardness salts from depositing as scale on heat-transfer surfaces in cooling and process water.
What grades and forms of ATMP are available?
ATMP is commonly supplied as an aqueous solution at various active concentrations and as a solid/powder form. Specify the active content and physical form you need so we quote the correct material with a conforming CoA.
What is the HS code for amino trimethylene phosphonic acid?
ATMP classifies under HS 2931.49 (non-halogenated organo-phosphorus derivatives, other). RawSource ships bulk in drums, totes, and IBCs; request a bulk quote with SDS and CoA for your volume and destination.
