What is edtmpa?

Answer 1

EDTMPA is white crystal powder at room temperature, with melting point 215-217℃, hard to be dissolved in water, the solubility is less that 5% at room temperature, easy dissolved in ammonia. EDTMPA has strong metal ion chelating capacity, whose chelating constant with cuprum ion is larger than that of EDTA. EDTMPA has high capacity for chelating metal ions. The complex constant with Cu is the largest in all chelating agents including EDTA. EDTMPA is a kind of high-pure grade reagent and innocuous, it can be used as detergent 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 EDTMPA largely exceed that of EDTA and DTPA, and can replace EDTA for chelating agent at almost any situation. Information Source From http://www.thwater.net/01-EDTMPA.htm

Answer 2

EDTMPA is short for Ethylenediaminetetramethylene phosphonic acid, which is a chemical compound commonly used as a sequestrant and chelating agent in various industrial and water treatment applications. It is effective in binding and removing metal ions to prevent scale formation in water systems.
