Iodine monochloride (ICl) is a reactive interhalogen compound used as a selective halogenating agent in organic synthesis, particularly for introducing chlorine or iodine into molecules. In analytical chemistry, iodine monochloride is the key reagent in Wijs solution, which is used to determine the iodine value of fats and oils. It is supplied as a 1 molar solution in dichloromethane for controlled reactivity and stability. This product has a CAS number of 7790-99-0, a molecular formula of ICl, and a molecular weight of 162.36 g/mol. It must be stored at ambient conditions and handled with caution, as it carries a "Danger" signal word.
