Properties:
EDTMPA is
white crystal powder at room temperature, with melting point
******7℃, 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.
