Ethylene Diamine Tetra (Methylene Phosphonic Acid) Pentasodium Salt

EDTMP•Na5 is a powerful pentasodium salt of a nitrogen-containing polyphosphonic acid. It is distinguished by its excellent chelating ability, forming stable complexes with a wide variety of metal ions, which is critical for preventing scale formation and controlling mineral deposition .

This chelating agent is a subject of interest in water treatment research due to its effectiveness in controlling water hardness. Its high affinity for metal cations makes it a valuable tool for industrial applications that require a robust sequestrant to prevent scale buildup and corrosion in challenging water systems .
