General Description

Deep purple-blue powder.

Air & Water Reactions

Azo dyes can be explosive when suspended in air at specific concentrations. Slightly water soluble.

Reactivity Profile

CI 23790 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. Cleavage of the diazo group by reducing agents may lead to benzidine production.

Fire Hazard

Flash point data for CI 23790 are not available; CI 23790 is probably combustible.
