Description
p-Aminodiphenylamine hydrochloride was formerly
used as a hair dye. Sensitization, when deteeted by
patch testing, is relatively low in hairdressers.
Chemical Properties
Dark grey flake
Uses
4-Aminodiphenylamine is used as an oxidation dye color in hair
dyes. It is also promoted as an efficient reagent for oxidase
enzymes, including glucose, lactate, xanthine, and lysine
oxidases.
Uses
p-Anilinoaniline is an antioxidant that has shown to cause a reduction of NOx emissions from soybean biodiesel powered DI diesel engines but has increased CO and HC emissions. It is also used to produce dyes, pharmaceuticals, and photographic chemicals and frmerly used as a hair dye.
Uses
Dye intermediate, pharmaceuticals, photographic chemicals.
Definition
ChEBI: An aromatic amine that is the 4-amino derivative of diphenylamine.
General Description
Odorless purple-black solid or flake or dark purple chips.
Air & Water Reactions
Insoluble in water.
Reactivity Profile
4-Aminodiphenylamine is incompatible with strong oxidizers. 4-Aminodiphenylamine is also incompatible with strong acids. 4-Aminodiphenylamine may react with plastics.
Fire Hazard
4-Aminodiphenylamine is combustible.
Contact allergens
This substance was formerly used as a hair dye.
Sensitization, when detected by patch testing, is relatively
low in hairdressers.
Purification Methods
It crystallises from EtOH with m 66o, and from ligroin with m 75o. It can be distilled at high vacuum. [Beilstein 13 IV 113.]
