1. performance and use:
EDTMPA is a white crystalline powder at room temperature, melting point 215-217 ° C, slightly soluble in water, solubility less than 5% at room temperature, soluble in ammonia.
EDTMPA has a strong ability to chelate metal ions, and its complexation constant with copper ions is large among all chelators including EDTA. EDTMPA is a high-purity reagent and non-toxic. It can be used as a semiconductor chip cleaning agent in the electronics industry to manufacture integrated circuits. It is a carrier for radioactive elements in the pharmaceutical industry for the inspection and treatment of diseases. The chelation ability of EDTMPA far exceeds that of EDTA. With DTPA, EDTMPA can be used in almost all places where EDTA is used as a chelating agent.
