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.
Uses4-Nitro-o-phenylenediamine is used to study the in vitro activation of 4-nitro-o-phenylenediamine into a potent mutagen in Salmonella typhimurium strain TA98
Uses4-Nitro-o-phenylenediamine was used to study the in vitro activation of 4-nitro-o-phenylenediamine into a potent mutagen in Salmonella typhimurium strain TA98 .
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.
Biochem/physiol Actions4-Nitro-o-phenylenediamine is a direct-acting mutagen.
Safety ProfileModerately toxic by ingestion. An experimental teratogen. Other experimental reproductive effects. Mutation data reported. Questionable carcinogen. When heated to decomposition it emits toxic fumes of NOx,.
Purification MethodsCrystallise the diamine from water. [Beilstein 13 IV 75.]
