C6H20 N2O12P4
Molecular weight: 436.13
Structural Formula:
Properties:
Ethylene
Diamine Tetra (Methylene Phosphonic Acid)
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.
Ethylene
Diamine Tetra (Methylene Phosphonic Acid)
has strong metal ion chelating capacity, whose chelating
constant with cuprum ion is larger than that of EDTA.
Ethylene
Diamine Tetra (Methylene Phosphonic Acid)
has high capacity for chelating
metal ions. The complex constant with Cu is the largest in
all chelating agents including EDTA.
Ethylene
Diamine Tetra (Methylene Phosphonic Acid)
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
Ethylene Diamine Tetra (Methylene Phosphonic Acid)
largely exceed that of EDTA and DTPA, and can replace EDTA
for chelating agent at almost any situation.
