Products Description of Disodium edetate dihydrate CAS#6381-92-6

Disodium ethylenediaminetetraacetate (also known as EDTA disodium) is a powerful chelating agent. Due to its high stability constant and wide range of coordination properties, it can almost form stable water-soluble complexes with most metal ions (such as iron, copper, calcium, magnesium, etc., polyvalent ions) outside of Chemicalbook, eliminating harmful reactions caused by metal ions or their effects..
