Basic Orange 2 (CAS NO.532-82-1) is red-brown powder, large black shiny crystals with a green luster or purple powder. It is slightly soluble in water. Basic Orange 2 is an azo compound. Azo dyes can be explosive when suspended in air at specific concentrations. Toxic gases are formed by mixing compounds containing azo groups 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. Basic Orange 2 is incompatible with strong oxidizing agents. Flash point data for Basic Orange 2 are not available. It is probably combustible.
