一氯化碘是一种卤素间化合物。它与乙基苯、异丙基苯和叔丁基苯形成各种络合物。已经评估了形成这些配合物的平衡常数。它在极性溶剂中溶解时提供导电溶液。它与胸苷、3-单烷基和3,3′，5′-三烷基取代胸苷的反应表明，它有助于胸苷的去糖基化、异头化和异构化。

Iodine monochloride is an interhalogen compound. It forms various complexes with ethyl, isopropyl and t-butylbenzenes. Equilibrium constants for the formation of these complexes have been evaluated. It affords electrically conducting solution on dissolution in polar solvents. Its reaction with thymidine, 3-mono- and 3,3′,5′-trialkylsubstitued thymidine showed that it helps in deglycosylation, anomerization and isomerization of thymidine.

Application：

Iodine monochloride is used as a catalyst in organic synthesis. It is the source of electrophilic iodine in the synthesis of certain aromatic iodides. It is used to determine the iodine value of a substance.

Iodine monochloride (ICl) may be employed for the halogenation of methoxy and dimethoxybenzenes. It may be used for the synthesis of flavones.
Iodine monochloride may be used in the synthesis of the following: 2-(4-haloisoquinolin-1-yl)ethanol derivatives；5-iodosalicylaldehydes；5-aryl-6-iodo-8-phenylpyrazolo[1,5-c]-1,2,4-triazolo[4,3-a]pyrimidines；(±)-1-cyclohexyl-4-iodo-3-methoxybutan-1-ol；(±)-4-Iodo-3-methoxy-1-phenylbutan-1-ol.
