 1,1'-Azobis(cyanocyclohexane) (CAS NO.2094-98-6) is self-decomposition or self-ignition, which may be triggered by heat, chemical reaction, friction or impact. It may be ignited by heat, sparks or flames. 1,1'-Azobis(cyanocyclohexane) is an azo compound that can detonate. This applies in particular to organic azides that have been sensitized by the addition of metal salts or strong acids. Toxic gases are formed by mixing materials of this class with acids, aldehydes, amides, carbamates, cyanides, inorganic fluorides, halogenated organics, isocyanates, ketones, metals, nitrides, peroxides, phenols, epoxides, acyl halides, and strong oxidizing or reducing agents. Flammable gases are formed by mixing materials in this group with alkali metals. Explosive combination can occur with strong oxidizing agents, metal salts, peroxides, and sulfides.
