General DescriptionBluish-black powder.
Air & Water ReactionsAzo dyes can be explosive when suspended in air at specific concentrations. Slightly soluble in water.
Reactivity ProfileBENZOAZURINE 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 HazardFlash point data are not available for BENZOAZURINE, but BENZOAZURINE is probably combustible.
Properties and Applicationsblue. Soluble in water for purple red to blue, soluble in soluble fiber element, soluble in ethanol, insoluble in other organic solvents. The strong sulfuric acid for blue, blue for red after diluted. The dye solution to join strong hydrochloric acid for purple, have precipitation; Add thick sodium hydroxide solution for red light purple.
