Ethylenediaminetetraacetic acid disodium salt dehydrate by MP Biomedicals is a high grade reagent. EDTA is a chemical used for both industrial and medical purposes. This reagent is available as a colourless powder which is soluble in water. It acts as a hexadentate ligand and chelating agent, with its ability to “sequester” metal ions such as Ca2+ and Fe3+. After being bound by EDTA into a metal complex, the metal ions remain in solution but exhibit diminished reactivity. CAS Number: 6381-92-6 Quantity provided: 500 gm per bottle Chemical formula: C10H14N2Na2O82H2O Molecular weight: 372.24 Ethylenediaminetetraacetic acid disodium salt dehydrate has a wide range of applications in biological and chemical industries. It is an excellent chelator of divalent cations and inhibits enzymes, such as metalloproteases, that require divalent cations for activity. In the textile industry, it prevents metal ion impurities from modifying color of dyed products. EDTA is also added to some foods as a preservative or stabilizer to prevent catalytic oxidative decolouration catalysed by metal ions. Ethylenediaminetetraacetic acid disodium salt dehydrate has been used to prepare TE buffer, as an anticoagulant, and as a constituent of Flow buffer. In analytical chemistry, EDTA is used in complexometric titrations. These reagents are suitable for industrial and research applications.
