| Description & Application | EDTMPA is a white crystalline powder at room temperature. Its melting point is 215-217 C. It is slightly soluble in water, and its solubility is less than 5% at room temperature. It is easy to dissolve in ammonia. EDTMPA has a strong ability to chelate metal ions, and its complex constant with copper ions is the largest among all chelating agents including EDTA. EDTMPA is a high-purity reagent and non-toxic. It can be used as a cleaning agent for semiconductor chips in the electronic industry to manufacture integrated circuits. It can be used as a carrier of radioactive elements in the pharmaceutical industry to check and treat diseases. The chelating ability of EDTMPA is much higher than that of EDTA and DTPA, and can be replaced by EDTMPA in almost all places where EDTA is used as chelating agent. |
