Application
Chelator of divalent cations. Inhibits enzymes, such as metalloproteases, that require divalent cations for activity.
Ethylenediaminetetraacetic acid disodium salt dehydrate can be used to study molecular biology, biochemicals, solutions and reagents, biological buffers, DNA and RNA purification, inorganic salts, essential chemicals and chelators. Ethylenediaminetetraacetic acid disodium salt dehydrate has been used in a study to advance monitoring of illegal thyreostatic drugs in livestock. Ethylenediaminetetraacetic acid disodium salt dehydrate has also been used in a study for the determination of 232Th in seawater by ICP-MS after preconcentration and separation using a chelating resin.
