| A food azo-dye, a liver and urinary bladder carcinogen for rodents and a potent contact allergen and sensitizer for humans. Genotoxic and carcinogenic. Dyes and metabolites, Environmental Testing. | |||||||||||||||||||||||
| Preparation | Aniline diazo, and Naphthalen-2-ol?coupling. | ||||||||||||||||||||||
| ChEBI: Sudan I is an azo compound. It has a role as a dye. It is functionally related to a 2-naphthol. | |||||||||||||||||||||||
| General Description | Dark reddish-yellow leaflets or orange powder. Slight odor. | ||||||||||||||||||||||
| Azo dyes can be explosive when suspended in air at certain concentrations. Insoluble in water. | |||||||||||||||||||||||
| Reactivity Profile | Sudan I 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. Sudan I is incompatible with strong oxidizing agents and strong acids . | ||||||||||||||||||||||
| Flash point data for Sudan I are not available; however, Sudan I is probably combustible. | |||||||||||||||||||||||
| Flammability and Explosibility | Not classified | ||||||||||||||||||||||
| Experimental reproductive effects. Questionable carcinogen with experimental carcinogenic, neoplastigenic, and tumorigenic data. Mutation data reported. When heated to decomposition it emits toxic fumes of NOx. Used for coloring hydrocarbon solvents, oils, fats, waxes, shoe and floor polishes, and gasoline | |||||||||||||||||||||||
| Properties and Applications | Red light yellow. Melting point 134 ℃. Soluble in ethanol (for orange), acetone and benzene, insoluble in water. The strong sulfuric acid for product red, diluted for orange, precipitation; In the hot strong hydrochloric acid solution for red, HCL after cooling for the crystallization variegated dark green, but released a few separate hydrogen: and C.I. Solvent Yellow and the same chemical structure. Used for dyeing and printing of polyester fibers.
