Safety Information
Sodium periodate Usage And Synthesis
  • Chemical Propertieswhite powder
  • Chemical PropertiesSodium periodate Na2H3IO6, is formed by reaction of sodium iodate plus sodium hydroxide plus chlorine (sodium chloride also formed), and the periodate separates as crystals from the medium. In solution, it is stated, periodate gradually forms ozone and iodate at the ordinary temperatures.
  • UsesSodium Periodate is the sodium salt of periodic acid used to oxidize cellulose. Sodium Periodate oxidation is often used to selectively label RNA, saccharides and other compounds with vicinal diols.
  • UsesOxidimetric standard; determination of manganese.
  • DefinitionChEBI: An inorganic sodium salt having periodate as the counterion.
  • HazardFire risk in contact with organic materials. Toxic by ingestion.
  • Purification MethodsRecrystallise it from hot water. [Willard Inorg Synth I 170 1939, Bernays Inorg Synth II 212 1946.]
