EDTMP has a strong ability to chelate metal ions, and its complexation constant with copper ions is the largest among all chelating agents including EDTA. EDTMP is a high-purity reagent and non-toxic. It can be used as a cleaning agent for semiconductor chips in the electronics industry to manufacture integrated circuits; It is used as a carrier of radioactive elements in the pharmaceutical industry to check and treat diseases; The chelating capacity of EDTMP is much higher than that of EDTA and DTPA, and EDTMP can be used to replace EDTMP in almost all places where EDTA is used as chelating agent.
