At NINGBO INNO PHARMCHEM CO.,LTD., we believe in providing comprehensive knowledge about the chemicals we supply. Ethylenediaminetetraacetic Acid (EDTA) is an organic compound characterized by its powerful chelating ability. Its chemical formula, C10H16N2O8, highlights its structure as an aminopolycarboxylic acid. This structure allows EDTA to form highly stable, water-soluble complexes with a wide range of metal cations, including divalent and trivalent ions.

The mechanism behind EDTA's effectiveness lies in its hexadentate nature, meaning it can bind to a metal ion through six donor atoms (two nitrogen and four oxygen atoms). This forms a cage-like structure around the metal ion, effectively sequestering it. The EDTA chemical properties, such as its high stability constants for many metal complexes, are fundamental to its diverse applications across industries. For instance, its ability to keep iron soluble at neutral pH is crucial for its use in agriculture and certain industrial processes.

The primary synthesis route for EDTA involves the reaction of ethylenediamine with formaldehyde and sodium cyanide. This multi-step process yields the tetrasodium salt, which can then be converted into other forms, including the free acid. Understanding the EDTA synthesis process is important for ensuring product purity and consistency. NINGBO INNO PHARMCHEM CO.,LTD. adheres to strict quality control measures throughout the production and supply chain to deliver high-quality EDTA that meets the exacting standards of our clients worldwide.
