Ethylene Diamine Tetra (Methylene Phosphonic Acid)

EDTMPA (Solid)


CAS No.: 1429-50-1                                                 EINECS No.: 215-851-5

Molecular Formula: C6H20N2O12P4                             Molecular Weight: 436.13

RIDADR: UN 3261 8/PG II

Structural Formula:

 

EDTMPA

 

Properties: 

EDTMPA is white crystal powder at room temperature, with melting point 215-217℃, easy dissolved in ammonia, but hard to be dissolved in water: the solubility is less that 5% at room temperature.

EDTMPA has a strong ability to chelate metal ions, and its complexation constant of copper ion is the largest of all chelating agents, including EDTA.


Applications:

EDTMPA is high-pure grade and innocuous reagent. It can be used as detergent of semiconductor chip to prepare integrated circuit in electronics industry, as carrying agent for radioelement for inspection and therapy of disease in medical industry. The chelating capacity of EDTMPA largely exceed that of EDTA and DTPA, and can replace EDTA for chelating agent at almost any situation.
