EDTMPA is white crystal powder at room temperature, with melting point 215-217°C, 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 fchelating 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 innocuous, it can be used as detergent in semiconductchip to prepare integrated circuit, as carrying agent fradioelement in medical industry, as agent finspection therapy. The chelating capacity of EDTMPA largely exceed that of EDTA DTPA, can replace EDTA fchelating agent at almost any situation.
