SUDAN II Chemical Properties,Uses,Production
Chemical Properties
Red to orange-brownish powder
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.
Preparation
mixed N,N-dimethylaniline diazotization, and Naphthalen-2-ol coupling.
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.
Safety Profile
Questionable carcinogen with experimental carcinogenic data. Mutation data reported. When heated to decomposition it emits toxic fumes of NOx.
