【Reactivity Profile】

C.I. PIGMENT RED 23(6471-49-4) is sensitive to light and may be sensitive to heat. This compound is incompatible with strong oxidizing agents. . C.I. PIGMENT RED 23(6471-49-4) 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. Insoluble in water.
【Fire Hazard】

Flash point data for this chemical are not available. C.I. PIGMENT RED 23 is probably combustible.
