EDTA, Disodium Salt, Dihydrate is an extensively used chelator of divalent cations such as Ca2+. Its melting point is 240ºC. It has good solubility in water, acidic solution, hardly soluble in organic solvents such as alcohol or ether etc. EDTA (Ethylenediaminetetraacetic acid) is a chelating agent, a general chemical, and a sequestrant.
|Appearance||White powder Size:20 mesh|
In molecular biology applications, it is used to minimize metal ion contaminants. Also it used to facilitate enzymatic reactions that could be inhibited by heavy metal traces. Inhibits enzymes, such as metalloproteases, that requires divalent cations for activity.
EDTA-2Na is used in detergent, liquid soap, shampoo, agricultural chemicals, fixer solution for development of color film, water cleaner, pH modifier. When stating the redox reaction for the polymerization of butyl benzene rubber, it is used as part of activator for the complexation of metal ion and control of polymerization speed.
