What is Sodium edetate

Ethylenediaminetetraacetic acid (EDTA) white crystalline powder. Soluble in water and acid, insoluble in alcohol, benzene and chloroform, containing 4 carboxyl groups, generally can form di-salt, tri-salt and tetra-salt. Common EDTA salts are disodium EDTA (EDTA-2Na), tetrasodium EDTA-4Na (EDTA-4Na), dipotassium EDTA-2K (EDTA-2K) and EDTA triacetate Potassium (EDTA-3K). Tetrasodium ethylenediaminetetraacetate (EDTA-4Na) is a multifunctional organic small molecule containing amino and carboxyl groups.
