At ambient temperature, it is white crystalline powder with melting point of 215‑217 ℃. Slightly soluble in water, solubility below 5% at room temperature, freely soluble in ammonia water.
Alias: Ethylenediamine Tetramethylene Phosphonic Acid
Molecular Formula: C₆H₂₀O₁₂N₂P₄
Relative Molecular Mass: 436
At ambient temperature, it is white crystalline powder with melting point of 215‑217 ℃. Slightly soluble in water, solubility below 5% at room temperature, freely soluble in ammonia water.
It exhibits strong metal‑ion chelating capacity. Its complex constant with copper ion ranks among the highest of all chelators including EDTA. As high‑purity and non‑toxic reagent, it can be used as cleaning agent for semiconductor chips in electronic industry for integrated circuit manufacturing. In pharmaceutical industry, it acts as carrier for radioactive elements for disease diagnosis and treatment. EDTMPA possesses far stronger chelating performance than EDTA and DTPA, and can replace EDTA in almost all applications where EDTA is used as chelating agent.
