4-Chloro-2-nitroaniline Usage And Synthesis
Chemical Propertiesbright orange powder
UsesA nitro-aromatic amine with mutagenicity and carcinogenicity
Uses4-Chloro-2-nitroaniline is used almost exclusively as an intermediate in the synthesis of pigments. The greatest potential for human exposure to 4-chloro-2- nitroaniline is in production and use of pigments made from the compound.
General DescriptionBright orange powder.
Air & Water ReactionsInsoluble in water.
Reactivity Profile4-Chloro-2-nitroaniline forms explosive products on reaction with nitric acid. Can react with oxidizing agents.
HazardToxic by ingestion and inhalation.
Fire Hazard4-Chloro-2-nitroaniline is probably combustible.
Purification MethodsCrystallise the aniline from hot H2O (m 115.8-116o), EtOH, EtOH/H2O or *C6H6, and dry it for 10hours at 60o in vacuo. It has m 115.5-116o after sublimation. [Beilstein 12 H 729, 12 I 355, 12 II 396, 12 III 1649, 12 IV 1669.]
