| Hazard Information | Back Directory | [Chemical Properties]
dark red to bordeaux fine powder | [Uses]
A stain used in histology and in Masson’s trichrome stain. | [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
. | [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. | [Preparation]
2,4-Dimethylbenzenamine diazo, coupled with 3-Hydroxynaphthalene-2,7-disulfonic acid. | [Properties and Applications]
colourful red yellow light. Soluble in water for red orange to red, hardly soluble in ethanol and acetone, insoluble in other organic solvents. The strong sulfuric acid are blushing to wine red, yellow and red for diluted. In water solution to join strong hydrochloric acid have red precipitate; Join nitric acid by bright red to orange; Add thick sodium hydroxide solution into orange brown; Add 10% sodium hydroxide solution for palm red.
