Insoluble in water.

Reactivity Profile

4,4'-Oxybis(benzenesulfonyl hydrazide) is an azide. 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.

Flammability and Explosibility

Not classified

Safety Profile

Mutation data reported. A flammable solid. When heated to decomposition it emits very toxic fumes of NOx and SOx
