Safety Information
Sudan I Usage And Synthesis
  • Chemical Propertiesorange-red powder
  • UsesA food azo-dye, a liver and urinary bladder carcinogen for rodents and a potent contact allergen and sensitizer for humans.
  • General DescriptionDark reddish-yellow leaflets or orange powder. Slight odor.
  • Air & Water ReactionsAzo dyes can be explosive when suspended in air at certain concentrations. Insoluble in water.
  • Reactivity ProfileSudan 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 .
  • Fire HazardFlash point data for Sudan I are not available; however, Sudan I is probably combustible.
  • Safety ProfileExperimental 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
  • Purification MethodsCrystallise the dye from EtOH. It forms Cu and Ni salts. [Beilstein 16 H 162, 16 I 254, 16 II 70, 16 III 129, 16 IV 228.]
