Orange-red powder | [Uses]
4-Nitro-1,2-phenylenediamine is a hair dye constituent with potential mutagenic activity. | [Application]
4-Nitro-1,2-phenylenediamine is a hair dye constituent with potential mutagenic activity. It is used in oxidation hair dye formulations at a maximum concentration of 1.0 %, which after mixing typically in a 1:1 ratio with hydrogen peroxide just prior to use, corresponds to a concentration of 0.5% upon application. | [Definition]
ChEBI: The primary amino compound that is 1,2-phenylenediamine (o-phenylenediamine) substituted at the 4- (para-) position by a nitro group. | [Preparation]
Prepared by reduction of 2,4-dinitroaniline using H2S in ammonia water. | [Production Methods]
Commercial 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. | [Biochem/physiol Actions]
4-Nitro-o-phenylenediamine is a direct-acting mutagen. | [Purification Methods]
Crystallise the diamine from water. [Beilstein 13 IV 75.] | [References]
