Ethylenediaminetetraacetic acid（EDTA）, chemical formula C10H16N2O8, molecular weight 292.24, CAS number 60-00-4, EINECS registration number 200-449-4.
Ethylenediaminetetraacetic acid (EDTA) is an organic compound, which is a white powder at room temperature and pressure. It is a chelating agent that can bind with Mg2+, Ca2+, Mn2+, Fe2+, and other divalent metal ions. As most nucleases and some proteases need Mg2+ for their action, 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.
EDTA is an important complexing agent. EDTA is widely used, can be used as color photographic material processing bleaching fixing solution, dyeing auxiliary, fiber processing auxiliary, cosmetic additives, blood anticoagulant, detergent, stabilizer, a synthetic rubber polymerization initiator, EDTA is the representative substance of chelating agent. It can form stable water-soluble complexes with alkaline earth metals, rare earth elements, and transition metals. In addition to sodium salts, there are ammonium salts and iron, magnesium, calcium, copper, manganese, zinc, cobalt, aluminum, and other various salts, each of these salts has different uses. In addition, EDTA can also be used to make harmful radioactive metals from the human body quickly excreted to play a detoxifying effect. EDTA is also an important indicator but can be used to titrate metal nickel, copper, etc., when used with ammonia, in order to play the role of the indicator.
