Molecular Formula: C3H7NO9P3Na5

Molecular weight: 409

Structural Formula:

Properties:

ATMP•Na5 is the salt of ATMP, it can inhibit calcium carbonate particularly in water treatment system .

ATMP•Na5 can be used in circulating cool system in power plant, oil refinery plant and oilfield refill

water system .

ATMP • Na5 is a general low cost scale inhibitor, it has good corrosion inhibition to zinc salt and

phosphate, its chelating ability is good as well.
