Scale inhibitor EDTMPA
Product Description
EDTMPA has a strong metal ion chelation capacity of copper ions and the complex is a constant, including all of the
chelating agent EDTA, the largest. EDTMPA for highpurity reagents and drugfree, the electronics industry in
semiconductor chips can be used as cleaning agent used in the manufacture of integrated circuits; in the
pharmaceutical industry for bringing the radioactive agents for examination and treatment of disease; EDTMPA the
chelating ability is far more than EDTA And DTPA, in almost all use of chelating agent EDTA for the places available
EDTMPS alternative.
Properties
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 highpure 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
