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, with strong 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.
