Molecular weight: 436.13
Structural Formula:
Properties:
EDTMPA
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.
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.
