Ethylenediaminetetraacetic acid CAS#60-00-4

Ethylenediaminetetraacetic acid CAS#60-00-4

Basic Information

Ethylenediaminetetraacetic acid
EDTA

Ethylenediaminetetraacetic acid is a polydentate chelating agent whose two nitrogen and four oxygen donor atoms can surround metal ions at six coordination sites. The resulting complexes are highly stable, allowing controlled sequestration and deactivation of dissolved metals. EDTA is used in analytical chemistry and metal-ion control, including complexometric procedures and formulations intended to bind unwanted metal species. It is also described as an ingredient in heavy-metal treatment for farm animals.

product description

Strong Chelating Ability: EDTA can bind to metal ions at six different sites, forming highly stable complexes.


Multi-Functional Binding: It contains two nitrogen and four oxygen atoms, allowing versatile coordination with various metals.


Effective Metal Deactivation: EDTA’s strong grasp on metal ions can neutralize or deactivate them efficiently.


Reliable Stability: The hexadentate chelation structure ensures that the formed metal complexes remain stable under diverse conditions.


Product Application of Ethylenediaminetetraacetic acid CAS#60-00-4

Ethylenediaminetetraacetic Acid (EDTA) is a widely used polydentate ligand. In solution, its hydrogen atoms are easily dissociated to form the EDTA⁴⁻ anion. In this ionic form, EDTA has six coordinating atoms, including two nitrogen atoms and four oxygen atoms. EDTA can bind to metal ions through all six coordination sites, fully enveloping the metal ion and forming highly stable complexes. Its strong binding affinity for metal ions is often likened to a crab or lobster grasping an object with its claws, which gives rise to the term "chelation". As a hexadentate ligand, EDTA serves as an efficient chelating agent, capable of sequestering and deactivating metal ions at six binding sites simultaneously.


Product Application of Ethylenediaminetetraacetic acid CAS#60-00-4

Ethylenediamine-N,N,N',N'-tetraacetic Acid (EDTA) is a high-efficiency chelating agent capable of forming stable complexes with a variety of metal ions. It is commonly used for the treatment of lead and heavy metal poisoning in farm animals.
