Product Description
Disodium EDTA (CAS: 139-33-3) is the disodium salt of ethylenediaminetetraacetic acid, known for its strong chelating properties. This powerful agent binds to metal ions like calcium, magnesium, iron, and copper, forming stable, water-soluble complexes. Its ability to sequester these metal ions makes disodium EDTA essential in various industries, where it helps prevent metal-catalyzed reactions that could affect product stability and quality.
