application as a volumetric reagent (8). Iodine monochloride (1) has also been used as an iodinating agent without involving a catalyst. It has two crystalline forms α and β that contain non-planar chains of ICl (1) molecules arranged in a zig-zag manner (9). This compound (1) has high vapor pressure and, similar to I2 molecules, evaporates easily. While it has been used frequently, there is some hazard while
