Overview
EDTA-Na₂ (Disodium EDTA) is a widely used chelating agent capable of binding divalent and trivalent metal ions such as calcium, magnesium, iron, and copper. By sequestering metal ions, EDTA-Na₂ improves stability, consistency, and performance in a wide range of laboratory and industrial systems.
Due to its high solubility and broad compatibility, Disodium EDTA is commonly used in chemical processing, water treatment, cosmetics manufacturing, analytical laboratories, and formulation development.
