| Hazard Information | Back Directory | [General Description]
Red-brown powder, large black shiny crystals with a green luster or purple powder. | [Reactivity Profile]
C.I. BASIC ORANGE 2(532-82-1) is an azo compound. 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. This chemical is incompatible with strong oxidizing agents. | [Air & Water Reactions]
Azo dyes can be explosive when suspended in air at specific concentrations.Slightly soluble in water. | [Hazard]
Questionable carcinogen. | [Fire Hazard]
Flash point data for this chemical are not available. C.I. BASIC ORANGE 2 is probably combustible. | [Chemical Properties]

| [Purification Methods]
It is a red-brown powder which is recrystallised from H2O. It gives a yellow solution in conc H2SO4 which turns orange on dilution. Its solubility at 15o is 5.5% (H2O), 4.75% (EtOH), 6.0% (cellosolve), 9.5% (ethylene glycol), 0.005% (xylene) and is insoluble in *C6H6. The hydroiodide has m 184o (from EtOH) and the picrate forms red needles m 196o. [Muramatsu Bull Chem Soc Jpn 31 864 1958, Beilstein 6 IV 561.] |
