4,4'-Oxybis(benzenesulfonyl hydrazide) Usage And Synthesis

Uses

4,4''-Oxydibenzenesulfonyl Hydrazide can be used for an antimicrobial mask with an anti-fog function.

General Description

A colorless, crystalline solid with a geranium-like odor. Insoluble in water and denser than water. Flash point 239°F. Boiling point 257°F. Contact may irritate skin, eyes and mucous membranes. Moderately toxic by ingestion, inhalation and skin absorption. Readily ignited by sparks or flames and burns intensely and persistently.

Air & Water Reactions

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
