Usage And Synthesis

Chemical Properties

bright orange powder

Uses

A nitro-aromatic amine with mutagenicity and carcinogenicity

Uses

4-Chloro-2-nitroaniline is used as pharmaceutical intermediate.

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.

Preparation

4-Chloro-2-nitrobenzenamine of chlorine.

Production Methods

1,4-Dichloro-2-nitrobenzene is aminated at 165 ℃ by using a process similar to that described for 2- nitroaniline.

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.]
