4-Nitrobenzenamine diazotization, and Naphthalen-2-amine coupling. | [General Description]
Dull reddish blue to reddish violet solid or dark maroon powder. | [Air & Water Reactions]
Dust can be explosive when suspended in air at specific concentrations. Insoluble in water. | [Reactivity Profile]
1-[(4-nitrophenyl)azo]naphthalen-2-amine 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 1-[(4-nitrophenyl)azo]naphthalen-2-amine are not available. 1-[(4-nitrophenyl)azo]naphthalen-2-amine is probably combustible. | [Properties and Applications]
dark blue light red to dark red light purple. From ethanol to crystallize in the product is golden needle crystal, melting point 185.5 ℃ soluble in ethanol, acetone and toluene. In concentrated sulfuric acid to red light blue, dilution after magenta to red solution, there are red brown precipitation; In concentrated sodium hydroxide solution insoluble.
