Lvnon-303 Ethylene Diamine Tetra (Methylene Phosphonic Acid)EDTMPA
Alias: EDTA methylene phosphonic acid Dequest2040
C6H12O12N2P4 molecular formula molecular weigh436
First, with the use of performance:
EDTMPA room temperature for the white crystalline powder, melting point 215-217 C, micro-soluble in water, at room temperature solubility of less than 5%, soluble in water.
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 high-purity reagents and drug-free, 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.
