EDTA-ACID/2NA/4NA

The chemical formula of tetrasodium ethylenediaminetetraacetate is C10H12N2Na4O8, which is a white crystalline powder. It is soluble in water and acid, but insoluble in alcohol, benzene and chloroform. It is used as chelating agent, styrene-butadiene rubber polymerization initiator, acrylic fiber initiator, etc. It is a commonly used chelating agent. Its chemical name is tetrasodium salt and its appearance is white crystalline powder. It is a multifunctional complexing agent that can form stable complexes with metal ions.

Disodium ethylenediaminetetraacetate, also known as EDTA-2Na, is a good compounding agent in chemistry. The chemical formula is C10H14N2Na2O8, and the molecular weight is 336.206. It has six coordination atoms, and the complex formed is called a chelate. EDTA is often used in coordination titration, usually to measure the content of metal ions. EDTA has important uses in dye, food, pharmaceutical and other industries. Disodium EDTA is a tasteless, odorless or slightly salty white or milky white crystal or granular powder, odorless and tasteless. It is soluble in water and extremely insoluble in ethanol. It is an important chelating agent that can chelate metal ions in solution. It prevents discoloration, deterioration, turbidity and oxidative loss of vitamin C caused by metals, and also improves the antioxidant properties of oils (trace metals in oils such as iron and copper can promote the oxidation of oils).

Ethylenediaminetetraacetic acid (EDTA) is an organic compound with the chemical formula C10H16N2O8. It is a white powder under normal temperature and pressure. It is a chelating agent that can combine with divalent metal ions such as Mg2+, Ca2+, Mn2+, and Fe2+. Since most nucleases and some proteases require Mg2+ to function, it is often used as an inhibitor of nucleases and proteases; it can also be used to remove the inhibitory effect of heavy metal ions on enzymes. White, odorless, colorless crystalline powder, melting point 250°C (decomposition). Insoluble in ethanol and general organic solvents, slightly soluble in cold water, soluble in aqueous solutions of sodium hydroxide, sodium carbonate and ammonia. It can be dissolved in more than 5% of inorganic acids, and can also be dissolved in ammonia and 160 parts of boiling water. Its alkali metal salt is soluble in water.
