4-Amino-2-nitrophenol is a dark red crystalline or reddish-purple solid.??
4-Amino-2-nitrophenol has been used in dyeing human hair and animal fur. The typical concentration in the “semipermanent” hair dyes was estimated to be on the order of 0.1–1.0%.?? ??
Dark red plates, needles or reddish-purple powder. Melting point 125-127°C.??? ?? ??
Sensitive to oxidation upon prolonged exposure to air. Insoluble in water.?? ???
4-Amino-2-nitrophenol may react with strong oxidizing agents, strong bases, acid chlorides and acid anhydrides .????
Flash point data for 4-Amino-2-nitrophenol are not available. 4-Amino-2-nitrophenol is probably combustible.Safety Profile
Suspected carcinogen with experimental carcinogenic data. Very poisonous by intraperitoneal route. Moderately toxic by ingestion. A severe eye heated to decomposition it emits toxic fumes of NOx.??? ??
In dye formulation for furs and hairCarcinogenicity
Under the conditions of the bioassay, the compound was carcinogenic in male rats inducing transitional cell carcinomas of the urinary bladder (controls 0/15, lowdose 0/46, high dose 11/39). The same tumor was also observed in three dosed female rats and may have been associated with the administration of the chemical. No evidence of carcinogenic activity was found in the mice.?? ??

Incompatible with oxidizers (chlorates, nitrates, peroxides, permanganates, perchlorates, chlorine, bromine, fluorine, etc.); contact may cause fires or explosions. Keep away from alkaline materials, strong bases, strong acids, oxoacids, epoxides. It is unknown if this nitro compound is explosive; some are flammable and explosive, and the contact with alkali increases thermal sensitivity of these materials.4-???-2-?????? ?? ?? ? ???
