Azoxybenzene Specification

Azoxybenzene(CAS NO.495-48-7) is a bright yellow crystals or yellowish-brown solid.Dust may form an explosive mixture in air and it insoluble in water. 
It is an azo compound. Azo, diazo, azido compounds 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. however, Azoxybenzene(CAS NO.495-48-7) is probably combustible.
