Hazard Information

General Description
Orange-red crystals or a red powder.
Reactivity Profile
FD & C YELLOW NO. 6(2783-94-0) 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.
Air & Water Reactions
Azo dyes can be explosive when suspended in air at specific concentrations. Soluble in water.
Health Hazard
SYMPTOMS: It can cause enlargement of the caecum and weight loss.
Fire Hazard
Flash point data for this chemical are not available; however, FD & C YELLOW NO. 6 is probably combustible.
