EDTA-2Na

Disodium edetate dihydrate, commonly known as EDTA disodium salt or EDTA-Na₂·2H₂O,

is a chemical compound with the formula C₁₀H₁₄N₂Na₂O₈·2H₂O. It appears as a white

crystalline powder and is highly soluble in water. Disodium edetate is a chelating agent,

meaning it can form stable complexes with metal ions, which is one of its most significant properties.

The discovery of disodium edetate dates back to the 1930s when the chemist Frederick J. Koenig

synthesized ethylenediaminetetraacetic acid (EDTA) for the first time. EDTA was initially developed

for its ability to bind metal ions, particularly calcium and magnesium, leading to its early applications

in medicine and industrial processes. The disodium salt form of EDTA, which is more soluble and

easier to handle, became prominent in the following years, especially after its commercial production

began in the 1950s.
