EDTA Disodium Salts

EDTA Disodium Salt is the disodium salt form of ethylenediaminetetraacetic acid, commonly used as a chelating agent in pharmaceutical, industrial, and laboratory applications. It appears as a white, crystalline powder, soluble in water, and functions by binding to divalent and trivalent metal ions such as Ca²?, Mg²?, Fe³?, and Pb²?, forming stable, water-soluble complexes.

EDTA disodium salt is widely used in clinical settings as an anticoagulant, particularly in blood collection tubes, where it sequesters calcium ions to prevent clotting. In pharmaceutical formulations, it enhances stability by chelating trace metals that could catalyze degradation. Industrially, it’s used in water treatment, cosmetics, cleaning agents, and food preservation to control metal-catalyzed oxidation and scale formation.

EDTA-2Na is more effective in neutral to acidic solutions
