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