Disodium ethylenediaminetetraacetic acid, also called EDTA-2Na (CAS 6381-92-6/CAS 139-33-3), is a good compounding agent in chemistry. The chemical formula is C10H14N2Na2O8 and the molecular weight is 336.206. It has six coordinating atoms. The complex formed is called a chelate. EDTA is often used in coordination titration and is generally used to determine the content of metal ions. EDTA has important uses in industries such as dyes, foods, and pharmaceuticals.
Disodium edetate cas 6381-92-6/139-33-3 is tasteless, odorless or slightly salty white or milky white crystal or granular powder, odorless and tasteless. It is soluble in water and extremely difficult to dissolve in ethanol. It is an important chelating agent that can chelate metal ions in solution. It can prevent the discoloration, deterioration, turbidity and oxidation loss of vitamin C caused by metals, and can also improve the oxidation resistance of oils (the trace metals in oils such as iron and copper can promote the oxidation of oils).
