  • Applications

    Iodine monochloride (CAS 7790-99-0) is primarily used as an electrophilic iodinating and chlorinating reagent in organic synthesis, enabling the introduction of iodine and chlorine into activated arenes or alkenes to form iodinated or iodochlor intermediates. It is employed to prepare iodine-containing intermediates for pharmaceuticals, agrochemicals, and other organic syntheses, often as a precursor for cross-coupling reactions such as Suzuki and related transformations. In polymer and materials science, ICl can be used to iodinate monomers or polymers to introduce iodine, facilitating later functionalization by cross-coupling and adjusting material properties. In electronics and coatings/inks, iodinated products derived from ICl can serve as precursors for components in coatings or organic electronic materials. All applications are subject to local regulations and formulation limits.
