Ferric Sodium EDTA (CAS 15708-41-5) is a fascinating compound whose utility stems directly from its unique chemical structure and properties. As a key product for NINGBO INNO PHARMCHEM CO.,LTD., understanding its synthesis and characteristics is fundamental to appreciating its widespread applications. This detailed look explores the chemical profile and production methods of this vital chelating agent.

Chemically, Ferric Sodium EDTA is the ferric sodium salt of Ethylenediaminetetraacetic Acid. The EDTA molecule itself is a hexadentate ligand, meaning it can form strong coordinate bonds with metal ions using its four carboxylate groups and two amine nitrogens. In Ferric Sodium EDTA, iron is present in its ferric (Fe³⁺) state, chelated by the EDTA molecule, and accompanied by a sodium ion. This chelation results in a highly stable, water-soluble complex. Its typical appearance is a yellow-brown to brownish-yellow powder. The compound has a molecular weight of approximately 367.05 g/mol for the anhydrous form and around 421.1 g/mol for the trihydrate form. The pH of a 1% aqueous solution is typically in the range of 3.5 to 5.5, indicating its slightly acidic nature.

The synthesis of Ferric Sodium EDTA typically involves the reaction of ethylenediaminetetraacetic acid (EDTA) or its disodium salt with a ferric salt, such as ferric chloride, in the presence of a sodium source, like sodium hydroxide or sodium carbonate. The reaction conditions, including pH, temperature, and reactant molar ratios, are carefully controlled to ensure the formation of the desired stable chelate and to minimize by-products. The process often involves several steps of purification and drying to achieve the final powder product with the specified purity and particle size. Manufacturers like us optimize these synthesis routes to ensure efficient production and consistent quality.

The stability of the Ferric Sodium EDTA complex is crucial for its applications. The strong chelating power of EDTA protects the ferric ion from oxidation and precipitation across a relatively wide range of pH values, particularly in neutral to slightly acidic conditions common in many biological and industrial systems. This stability is what makes it an excellent source of iron for plant nutrition and a reliable component in food fortification and industrial catalysts.
