Hazard InformationBack Directory
[General Description]

A white to light colored solid substance. Insoluble in water and denser than water. Contact may irritate skin, eyes and mucous membranes. May be toxic by ingestion. May ignite and burn with an intense flame if exposed to high temperatures or flame.
[Reactivity Profile]

Self-decomposition or self-ignition may be triggered by heat, chemical reaction, friction or impact. SODIUM 2-DIAZO-1-NAPHTHOL-5-SULFONATE(2657-00-3) is a diazo derivative. 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.
[Air & Water Reactions]

Dust may form an explosive mixture in air. Insoluble in water.
[Chemical Properties]
