Properties :
EDT*** is a white crystal powder at room temperature, with a melting point at 215-217â„? It is hard to be dissolved in water, and its solubility is less that 5% at room temperature. It is easily dissolved in ammonia. It has a strong metal ion chelating capacity, and its chelating constant with cuprum ion is larger than that of EDTA.
It has a high capacity for chelating metal ions. The complex constant with Cu is the largest in all chelating agents including EDTA. It is a kind of high-pure grade reagent and innocuous. It can be used as ***ergent 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 EDT*** largely exceeds that of EDTA and DTPA, and can replace EDTA for chelating agent at almost any situation.
