Safety Information
Solvent Orange 2 Usage And Synthesis
  • Chemical Propertiesred needles or powder
  • General DescriptionRed needles or orange powder. Sublimes above 374°F.
  • Air & Water ReactionsAzo dyes can be explosive when suspended in air at specific concentrations. Insoluble in water.
  • Reactivity ProfileSolvent Orange 2 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 HazardFlash point data for Solvent Orange 2 are not available; however Solvent Orange 2 is probably combustible.
  • Safety ProfileConfirmed carcinogen with experimental carcinogenic and neoplastigenic data. Poison by intravenous route. Mildly toxic by ingestion. Mutation data reported. When heated to decomposition it emits toxic fumes of NOx. Used to color cosmetics, varnishes, oils, fats and waxes, petroleum products.
