Water Treatment Chemicals








Ethylene Diamine Tetra (Methylene Phosphonic Acid)
EDTMPA (Solid)
CAS No.  1429-50-1 
Molecular Formula:   C6H20 N2O12P4                Molecular weight:  436.13
Structural Formula:
  Properties: EDTMPA is white crystal powder at room temperature, with melting point 215-217℃, hard to be dissolved in water, the solubility is less that 5% at room temperature, easy dissolved in ammonia.EDTMPA has strong metal ion chelating capacity, whose chelating constant with cuprum ion is larger than that of EDTA.
EDTMPA has high capacity for chelating metal ions. The complex constant with Cu is the largest in all chelating agents including EDTA. EDTMPA is a kind of high-pure grade reagent and innocuous, it can be used as detergent in semiconductor chip to prepare integrated circuit, as carrying agent for radioelement in medical industry, and as agent for inspection and therapy. The chelating capacity ofEDTMPA largely exceed that of EDTA and DTPA, and can replace EDTA for chelating agent at almost any situation.  Specification:
