					Properties:
					
					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 and non-toxic, with strong ability to 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
