EDTA Properties and application:

Ethylenediamine tetraacetic acid (EDTA) is an organic compound, its chemical formula is C10H16N2O8, is white powder at room temperature and pressure. It is a chelating agent that can bind with divalent metal ions such as Mg2+, Ca2+, Mn2+ and Fe2+. As most nucleases and some proteases need Mg2+ for their functions, they are often used as inhibitors of nucleases and proteases. It can also be used to remove the inhibition of enzyme by heavy metal ions.

White odorless, tasteless, colorless crystalline powder, melting point 250℃ (decomposition). Insoluble in alcohol and general organic solvents, soluble in cold water (cold water speed is slower), hot water, soluble in sodium hydroxide, sodium carbonate and ammonia solution, soluble in 160 parts of 100℃ boiling water. Its alkali metal salts are soluble in water.

EDTA is an important complexing agent. EDTA has a wide range of uses, can be used as bleaching fixing solution for color photographic materials rinsing processing, dyeing AIDS, fiber processing AIDS, cosmetic additives, blood anticoagulants, detergents, stabilizers, synthetic rubber polymerization initiator, EDTA is the representative material of chelating agents. It can form stable water-soluble complexes with alkali metals, rare earth elements and transition metals. In addition to sodium salts, there are ammonium salts, iron, magnesium, calcium, copper, manganese, zinc, cobalt, aluminum and other salts, which have different uses. In addition, EDTA can also be used to detoxify harmful radioactive metals by rapidly excreting them from the body. It is also a water treatment agent. EDTA is also an important indicator, but it is used to titrate metal nickel, copper and so on. Only when it is used, it can play the role of indicator.
