Molecular Formula: C3H7NO9P3Na5    
Structural formula:

1. Performance and usage
ATMP·Na5 is the sodium salt solution of ATMP, which can prevent scale-forming salts in the water from forming scale, especially the formation of calcium carbonate scale. ATMP·Na5 is used for metal corrosion inhibition in boiler water treatment, oil field reinjection water systems, industrial and municipal clean water treatment and cooling water treatment. As a general low-cost scale inhibitor, ATMP·Na5 has a good corrosion inhibition effect on zinc salts and phosphates, and has good chelating properties.
