| Hazard Information | Back Directory | [Chemical Properties]
dark red or brown powder | [Uses]
For dyeing primarily cotton and viscose rayon: Colour Index vol. 2 (3rd ed., 1971) p 2101. As an analytical reagent in detection of Al, Mg, Hg, Ag, U; as a biological stain; as pH indicator, violet 1.2 to red 4.0. | [General Description]
Brown to dark red powder. | [Air & Water Reactions]
Azo dyes can be explosive when suspended in air at specific concentrations. Insoluble in water. | [Reactivity Profile]
BENZOPURPURIN 4B 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. | [Fire Hazard]
Flash point data for BENZOPURPURIN 4B are not available. BENZOPURPURIN 4B is probably combustible. | [Preparation]
3,3′-Dimethylbenzidine double nitriding, and 4-Hydroxynaphthalene-1-sulfonic acid (2 Moore) coupled. | [Properties and Applications]
red. Red powder. Soluble in water and red to red light for brown, soluble in soluble fiber element, ethanol and acetone, insoluble in other organic solvents. The strong sulfuric acid for red light blue, shallow green light blue for diluted, precipitation; In nitric acid solution for blue, yellow to brown. The dye solution to join strong hydrochloric acid for violet black, precipitation; Add thick sodium hydroxide solution for orange brown, have precipitation; Add 10% sodium hydroxide solution in red. Mainly used for cellulose fiber dyeing and printing.
