Osmium tetroxide, OsO//4, is the most important and most easily prepared compound of osmium. It is one of the few volatile oxides of a heavy metal and although the osmium is octavalent (of all elements only osmium and ruthenium reach as high an oxidation state) it is a reasonably controllable oxidizing agent. Most of its applications derive from this property. One of the major uses of the compound OsO//4 is for the oxidation of olefins. The compound is extensively used (normally in 2 per cent aqueous solution, often called osmic acid for cell and tissue studies, because of its unique fixation and staining properties. Its ability to passify iron electrodes provides corrosion protection in electrolytes.
