| | 4-Chloro-2-nitroaniline Usage And Synthesis |
| Chemical Properties | bright orange powder | | Uses | A nitro-aromatic amine with mutagenicity and carcinogenicity | | Uses | 4-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. | | Uses | 4-Chloro-2-nitroaniline is used as pharmaceutical intermediate. | | Preparation | 4-Chloro-2-nitrobenzenamine of chlorine. | | General Description | Bright orange powder. | | Air & Water Reactions | Insoluble in water. | | Reactivity Profile | 4-Chloro-2-nitroaniline forms explosive products on reaction with nitric acid. Can react with oxidizing agents. | | Hazard | Toxic by ingestion and inhalation. | | Fire Hazard | 4-Chloro-2-nitroaniline is probably combustible. | | Purification Methods | Crystallise 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.] |
