Description and Uses

Iodine monochloride is used to estimate theiodine values of fats and oils and as a topicalanti-infective (Merck 1996). For determination of iodine absorption number of fats Iodine monochloride is used as a catalyst in organic synthesis. It is the source of electrophilic iodine in the synthesis of certain aromatic iodides.
