  • Experimental Physico-chemical Properties
  • Miscellaneous
    • Appearance:

      pale yellow gas with a pungent odour Oxford University Chemical Safety Data (No longer updated) More details
      Pale-yellow to greenish gas with a pungent, irritating odor. NIOSH LM6475000
    • Stability:

      Stable. Extremely strong oxidant which may react violently withcombustible materials, including plastics, reducing agents and organic material.Reacts with water to form corrosive acids. Oxford University Chemical Safety Data (No longer updated) More details
    • Safety:

      Safety glasses, gloves. Use only in a thoroughlyventilated area. Do not use in the open laboratory or in any locationin which the concentration of the gas can rise above ppb levels. Do notuse until a full risk assessment has been made. Ensure there isno oil or grease in the gas handling system - if this is not donea violent reaction or explosion may occur. Equipment will requirepassivation before use. Oxford University Chemical Safety Data (No longer updated) More details
