Chloroiodide is a binary interhalogen compound composed of chlorine and iodine, primarily used as a selective reagent in organic synthesis, particularly for halogenation reactions and as a source of electrophilic iodine. It is also employed in analytical chemistry for specific titrations, notably as the active component of Wijs reagent for determining the iodine value of fats and oils. Chloroiodide has the CAS number 7790-99-0, with a molecular formula of ClI and a molecular weight of 162.36 g/mol. It must be stored between 2 to 8°C and carries a Danger signal word due to its hazardous nature. Molekula supplies Chloroiodide from research to bulk quantities with full documentation and ISO 9001:2015 traceability.
