EDTA-2NA CAS No.：6381-92-6

Efficient chelating agent: Ethylenediaminetetraacetic acid disodium salt (EDTA-2Na), also known as disodium edetate; Disodium EDTA; EDTA disodium salt, molecular formula: C10H14N2O8Na2•2H2O，Molecular weight: 372.24，CAS number: 6381-92-6; 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. Diethylenetriaminepentaacetic acid has low toxicity, with an oral LD50 of 2000 milligrams per kilogram in rats. EDTA-2Na is used as a chelating agent for metal ions. Test for calcium, magnesium, etc. Diethylenetriaminepentaacetic acid disodium salt (EDTA-2Na) be used in fields such as pharmaceutical industry, color development, and smelting of rare metals.
