Structural Formula:
Properties:
EDTMP 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.
EDTMP has strong metal
ion chelating capacity, whose chelating constant with cuprum
ion is larger than that of EDTA.
EDTMP has high capacity for chelating metal ions. The complex
constant with Cu is the largest in all chelating agents including
EDTA. EDTMP 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
EDTMP largely exceed that of EDTA and DTPA, and can replace
EDTA for chelating agent at almost any situation.
