| Definition | ChEBI: An organic sodium salt that is the disodium salt of 4-[(2,4-dimethylphenyl)diazenyl]-3-hydroxynaphthalene-2,7-disulfonic acid. Its use is largely confined to Masson's trichrome, where it gives a slight orange shading to the red of the cytoplasmic structure . |
| Preparation | 2,4-Dimethylbenzenamine diazo, coupled with 3-Hydroxynaphthalene-2,7-disulfonic acid. |
| General Description | Dark red crystals or red powder. |
| Air & Water Reactions | Azo dyes can be explosive when suspended in air at specific concentrations. Slightly soluble in water. |
| Reactivity Profile | ACID RED 26 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. ACID RED 26 is incompatible with strong oxidizing agents and strong acids . |
| Fire Hazard | Flash point data for ACID RED 26 are not available; however, ACID RED 26 is probably combustible. |
| Safety Profile | Moderately toxic by intraperitoneal route. Questionable carcinogen with experimental carcinogenic and tumorigenic data. Mutation data reported. When heated to decomposition it emits toxic fumes of NOx and SOx. |
