EDTA-2Na:Ethylenediaminetetraacetic Acid Disodium Salt

Ethylenediaminetetraacetic Acid Disodium Salt (EDTA-2Na), with the chemical formula C10H14N2Na2O8·2H2O, is a sodium salt of the widely used chelating agent, EDTA. It typically appears as a white, crystalline powder or granules and is highly soluble in water. This compound functions as a powerful sequestrating agent, capable of forming stable, water-soluble complexes with a broad spectrum of di- and trivalent metal ions. Its effectiveness across various pH ranges and its relative safety profile make it an indispensable component in industries ranging from cosmetics and detergents to food preservation and analytical chemistry.
