Frequently Asked Questions

What is EDTMPA used for?
This product can be used as a scale and corrosion inhibitor for steam boilers, a scale inhibitor for circulating cooling water, a stabilizer for peroxides, and a metal ion chelating agent for electroplating industries.
EDTMPA has a strong ability to chelate metal ions, and its complexation constant with copper ions is the largest among all chelating agents including EDTA. EDTMPA is a high-purity reagent and non-toxic. In the electronics industry, it can be used as a cleaning agent for semiconductor chips to manufacture integrated circuits. In the pharmaceutical industry, it can be used as a carrier of radioactive elements for inspection and treatment of diseases. The chelating ability of EDTMPA far exceeds that of EDTA and DTPA. EDTMPA can be used in almost all places where EDTA is used as a chelating agent.
