Details :Ethylene Diamine Tetra (Methylene Phosphonic Acid)EDTMPA (Solid)
EDTMPA
CAS No.: 1429-50-1 Molecular Formula: C6H20N2O12P4 Molecular weight: 436.13 Structural Formula: EDTMP·Na5
CAS No.: 7651-99-2 Molecular Formula: C6H15O12N2P4Na5 Molecular weight: 546.13 Structural Formula: Properties:
EDTMPA is Pale yellow solution 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 of EDTMPA largely exceed that of EDTA and DTPA, and can replace EDTA for chelating agent at almost any situation. Specification:
Package and Storage:
EDTMPA liquid: Normally In 250kg net Plastic Drum, IBC drum can also be used as required. EDTMPA solid: 25kg inner liner polyethylene (PE)bag, outer plastic woven bag,, or confirmed by clients. Storage for ten months in room shady and dry place. Safety Protection: Acidity, Avoid contact with eye and skin, once contacted, flush with water. |
