Product Parameters
Appearance: white crystal powder.
Characteristic:
EDTMPA is white crystal powder at room temperature, with melting point 215-217ºC, 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.
Main indexes:
Index | Standard |
Appearance | White crystal powder |
Active acid (as EDTMPA) by wt % | 96.0 min |
Total phosphonic acid(as PO43-) by wt % | 82.0 min |
Chloride (Cl-) % | 0.1 max |
Moisture by wt % | 2.0 max |
Fe by mg/L | 5.0 max |
pH (1% water solution) | 2.0 max |
Detailed Photos
Application
EDTMPA 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.
Important Notice
We normally list 2 years as the shelf life in our COA, the real shelf life can be slightly longer than 2 years if it's stocked in good condition (bags are sealed enough, away from direct sun-light, moisture and other incompatible chemical materials).
