• Physical Properties: Exists in two allotropic forms: red tetragonal allotropic modification (alpha form) and the yellow rhombic modification (beta form). The red iodide has a density 6.36 g/cm3 at 25°C; transforms to yellow form at 127°C; also converts to yellow form at –180°C; slightly soluble in water (100 mg/L at 25°C); moderately soluble in acetone and alcohol. The yellow iodide has a density of 6.09 g/cm3 at 27°C; melts at 259°C; vaporizes at 354°C; practically insoluble in water; low-to-moderately soluble in alcohol, benzene and other organic solvents.
• Uses: Mercury(II) iodide is used as an analytical reagent, in Nesslers reagent for the analysis of ammonia. The compound also is used in ointments for the treatment of skin diseases. In animal chemistry for preparation of Nessler's Reagent (alkaline mercuric potassium iodide solution). Mercury(II) iodide is is used for preparation of Nessler's reagent, used for detection of presence of ammonia. It is a semiconductor material, used in some x-ray and gamma ray detection and imaging devices operating at room temperatures. In veterinary medicine, it is used in blister ointments in exostoses, bursal enlargement, etc.
