Reaktivität anzeigen
PONCEAU 3R 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.
Hazard
Prohibited by FDA for use in foods, drugs,
cosmetics. Possible carcinogen.
Brandgefahr
Flash point data for PONCEAU 3R are not available; however, PONCEAU 3R is probably combustible.
Sicherheitsprofil
Confirmed carcinogen
with experimental carcinogenic and
tumorigenic data. Mutation data reported.
When heated to decomposition it emits
toxic fumes of NOx and SOx.
