Ethylenediaminetetraacetic acid disodium salt (EDTA-2NA),Cas:6381-92-6

Ethylenediaminetetraacetic acid disodium salt (EDTA-2NA),Cas:6381-92-6, Chemical formula: C10H14N2Na2O8 · 2H2O, molecular weight: 372.24, melting point: 252 º C, boiling point:>100 ° C; Among the salts of EDTA, disodium salt is the most important, which is an important complexing agent for complexing metal ions and separating metals. It can also be used in detergents, liquid soaps, shampoo, agricultural chemical sprays, bleaching fixatives for color sensitive material processing, water purification agents, pH regulators, anionic coagulants, etc. In the redox initiation system for styrene butadiene rubber polymerization, disodium EDTA is used as an active agent to chelate ferrous ions and control the polymerization reaction rate. This product has low toxicity, with an oral LD50 of 2000 milligrams per kilogram in rats. Used as a chelating agent for metal ions.
