May cause eye irritation. Potential Health Effects Eye: AIBN is produced from acetone cyanohydrin and hydrazinethen followed by oxidation: Avoid contact with eyes, skin, and clothing.

If victim is conscious and alert, give cupfuls of milk or water. May decompose explosively when heated or involved in a fire.

Vapors or dust may form explosive mixture with air. Harmful to aquatic organisms; may cause long-term adverse effects in the aquatic environment. May cause liver and kidney damage. During a fire, irritating and highly toxic gases may be generated by thermal abn or combustion.


Use adequate general or local explosion-proof ventilation to keep airborne levels to acceptable levels. R 2 Risk of explosion by shock, friction, fire or other sources of ignition. Remove from exposure to fresh air immediately.

Get medical aid if irritation develops or persists. Advanced stages may cause collapse, unconsciousness, coma and possible death due to respiratory failure.


Use with adequate ventilation. Acetone possible explosive decomposition ; Heptane possible explosion with the addition of heat Hazardous Decomposition Products: May cause respiratory tract irritation. Azo compounds Polymer chemistry Reagents for organic chemistry Radical initiators.


Above a given “control temperature” they decompose violently and catch fire. Keep away from sources of ignition.

Pyrolysis of AIBN without a trap for the formed 2-cyanopropyl radicals results in the formation of tetramethylsuccinonitrilewhich is highly toxic. Personal Protective Equipment Eyes: Wear appropriate protective clothing to prevent skin exposure. May cause central nervous system depression, characterized by excitement, followed by headache, dizziness, drowsiness, and nausea. Overview Properties Synthesis Route Precursor and Substance is shock sensitive and thermally unstable.

Wear appropriate protective gloves to prevent skin exposure. Views Read Edit View history. These radicals can initiate free-radical polymerizations and other radical-induced reactions.
