Red to orange-brownish powder | [General Description]
Red crystals. Insoluble in water. | [Air & Water Reactions]
Azo dyes can be explosive when suspended in air at specific concentrations. Insoluble in water. | [Reactivity Profile]
SUDAN II is an azo compound. Toxic gases are formed by mixing azo compounds 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. | [Uses]
Sudan II is a fat soluble red synthetic azo dye. Sudan II is reduced to potentially carcinogenic aromatic amines by human intestinal bacteria. Dyes and metabolites, Environmental Testing. | [Definition]
ChEBI:Sudan II is a member of azobenzenes. | [Preparation]
mixed N,N-dimethylaniline diazotization, and Naphthalen-2-ol coupling. | [Flammability and Explosibility]
Notclassified | [Properties and Applications]
red orange. Melting point 166 ℃ (from the glacial acetic acid crystallization out). Soluble in ethanol, acetone and benzene as the red orange. In concentrated sulfuric acid for cherry red, dilution still for cherry red, and then into the orange and red brown with precipitation; In concentrated nitric acid for brilliant orange solution, and then gradually become dark; In 10% of sodium hydroxide solution insoluble, for yellow sanguine. Dye alcohol solution to join concentrated hydrochloric acid for orange solution; Add sodium hydroxide to become red.
