Ethylenediamine dihydroiodide (EDDI) is a water-soluble salt derived from ethylenediamine and hydroiodic acid. It is a colorless to light yellow crystalline powder. The salt consists of the ethylenediammonium dication C2H4(NH3)22+ and iodide anions.
Application
EDDI is used as an additive in pet food and cattle feed with high bioavailability. Used to prevent iodine deficiency, this salt is one of the major uses of the element iodine.Lyday, Phyllis A.
