product description

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.
