  • Inhalation Risk:A harmful contamination of the air will be reached rather slowly on evaporation of this substance at 20 °C.
  • Effects of Short Term Exposure:The substance is severely irritating to the eyes, skin and respiratory tract. The substance may cause effects on the cellular respiration (inhibition). This may result in convulsions, cardiac disorders and respiratory failure. Exposure at high levels could cause death. Medical observation is indicated. The effects may be delayed.
  • Description Malonitrile is an aliphatic nitrile. It can release cyanide through either chemical or biological transformation. Malonitrile was used decades ago for treating certain forms of mental illness.
  • Uses In organic synthesis. Malononitrile is an important building block for the syntheses of pharmaceuticals (e.g. triamterene, adenine and methotrexate), thiamin (vitamin B1), pesticides dyestuffs for color photography and synthetic fibers (e.g. vinylidene cyanide). Product Data Sheet The chemical properties of malononitrile are determined by the nucleophilicity of the malononitrile anion, formed by deprotonation with relatively weak bases and by the two electrophilic cyano groups. Malononitrile is used in organic synthesis.
