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
is a high purity non-toxic reagent and non-toxic, with strong ability to chelating ability for metal ions, which can be used in the electronics industry as cleaning agent for semiconductor chips of integrated circuits, and as a carrier of radioactive elements in the pharmaceutical industry for the detection and treatment of diseases.
