For scientists and researchers in the chemical and biochemical fields, a deep understanding of molecular function is key to successful formulation and application. Disodium EDTA Dihydrate (CAS 6381-92-6) is a prime example of a compound whose utility is directly tied to its chemical structure and properties. As a supplier of high-quality chemical reagents, we aim to provide insights into the science behind our products.

Disodium EDTA Dihydrate is a salt of ethylenediaminetetraacetic acid, an aminopolycarboxylic acid. Its molecular formula, C10H14N2Na2O8•2H2O, hints at its complex structure. The EDTA molecule itself possesses six potential coordinating sites: two nitrogen atoms and four carboxylate groups. This hexadentate nature allows it to wrap around and strongly bind to metal cations, forming stable, water-soluble complexes. This process is known as chelation.

The ability to chelate metal ions is what makes Disodium EDTA Dihydrate so versatile. In biological systems, many enzymes require specific metal ions (like Mg2+, Ca2+, or Zn2+) as cofactors to function. EDTA can bind these metal ions, thereby inhibiting the enzyme activity. This property is utilized in molecular biology to deactivate metal-dependent enzymes that might degrade DNA or proteins. Conversely, in applications like blood collection, where clotting must be prevented, EDTA chelates calcium ions, which are essential for the clotting cascade. This controlled inhibition of metal ion activity is a hallmark of its effectiveness.

For R&D scientists and chemical formulators, understanding these mechanisms is crucial for optimizing product performance. When sourcing this chemical, seeking a supplier that guarantees high purity and well-defined specifications is essential. We provide Disodium EDTA Dihydrate with a purity exceeding 99%, ensuring that its chelating properties are reliable for your research and development projects.
