CAS No. 1429-50-1
Molecular Formula: C6H20 N2O12P4 Molecular weight: 436.13
Structural Formula:
Ethylene Diamine Tetra (Methylene Phosphonic Acid) 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. Ethylene Diamine Tetra (Methylene Phosphonic Acid) has strong metal ion chelating capacity, whose chelating constant with cuprum ion is larger than that of EDTA.
Ethylene Diamine Tetra (Methylene Phosphonic Acid) is a high purity non-toxic reagent, with strong chelating ability for metal ions, which can be used in the electronics industry as cleaning agent for semiconductor chips of integrated circuits, and as a carrier of radioactive elements in the pharmaceutical industry for the detection and treatment of diseases.
