EDTA Disodium salt, EDTA-2Na CAS 139-33-3 exists in white powder, easily soluble in water, but hard to soluble in organic solvents like alcohol or ethyl ether. The PH value of 5% (25℃) water solution is 4.0-6.0. EDTA is an important complexing agent for complexing metal ions and separation of metals, the materials used for processing color photographic materials, wash bleach fixer, and dyeing auxiliaries , fiber processing agents, cosmetic additives, pharmaceuticals, food, agriculture, chemical fertilizer production, blood anticoagulant, complexing agents, detergent, stabilizer, synthetic rubber, polymerization initiator and quantitative analysis of heavy metals etc.
