4-Nitro-o-phenylenediamine Usage And Synthesis
  • Chemical PropertiesOrange-red powder
  • Uses4-Nitro-1,2-phenylenediamine is a hair dye constituent with potential mutagenic activity.
  • DefinitionChEBI: The primary amino compound that is 1,2-phenylenediamine (o-phenylenediamine) substituted at the 4- (para-) position by a nitro group.
  • Production MethodsCommercial production of 4-nitro-o-PDA was first reported in the United States in 1946. Two U.S. companies were reported to produce undisclosed amounts of the chemical in 1975. U.S. imports of 4-nitro-o-PDA were reported to be about 1900 kg in 1973 and 1100 kg in 1975. 4-Nitro-o-PDAis used in fur dyes, inks, and semipermanent yellow hair coloring formulations requiring a yellow color component that does not involve the use of hydrogen peroxide in the color development.
    Occupational exposure to 4-nitro-o-PDA may occur through inhalation and dermal contact with this compound at workplaces where p-PDA is produced or used. The general population may be exposed to the compound via dermal contact, primarily through the use of hair dyes containing this compound.
  • General DescriptionDark red needles or red solid.
  • Air & Water ReactionsInsoluble in water.
  • Reactivity Profile4-Nitro-o-phenylenediamine is incompatible with strong oxidizing agents, strong acids, strong reducing agents, acid chlorides and acid anhydrides.
  • Fire HazardFlash point data for 4-Nitro-o-phenylenediamine are not available; however, 4-Nitro-o-phenylenediamine is probably combustible.
