EDTMP is normally delivered as its sodium salt, which exhibits good solubility in water. Used in Water treatment as an antiscaling and anti corrosion agent, the corrosion inhibition of EDTMP is 3–5 times better than that of inorganic polyphosphate. It can degrade to Aminomethylphosphonic acid.[2] It shows excellent scale inhibition ability under temperature 200 °C. It functions by chelating with many metal ions.
The anti-cancer drug Samarium (153Sm) lexidronam is also derived from EDTMP.
