Trisodium nitrilotriacetate monohydrate (Cat No.:R071411) is the hydrated form of a chelating agent composed of three carboxylate groups and one nitrogen atom, forming a tridentate ligand. It effectively binds metal ions such as calcium, magnesium, iron, and others, preventing their precipitation or interfering effects in aqueous solutions. Commonly used in industrial cleaning agents, detergents, and water treatment, it softens hard water and enhances the stability of formulations. In analytical chemistry, it serves in metal ion titration and complexometric analysis. Its water-soluble, biodegradable structure offers an alternative to more persistent chelators like EDTA.
