2-Chloro-4-nitroaniline Chemical Properties, Uses, Production

Chemical Properties

yellow crystalline powder

Uses

Intermediate in manufacture of dyes.

Synthesis Reference(s)

The Journal of Organic Chemistry, 51, p. 5039, 1986 DOI: 10.1021/jo00375a062

General Description

Yellow crystalline powder.

Air & Water Reactions

Insoluble in water.

Reactivity Profile

2-Chloro-4-nitroaniline can react with oxidizing materials.

Hazard

Toxic by ingestion and inhalation.

Health Hazard

TOXIC; inhalation, ingestion or skin contact with material may cause severe injury or death. Contact with molten substance may cause severe burns to skin and eyes. Avoid any skin contact. Effects of contact or inhalation may be delayed. Fire may produce irritating, corrosive and/or toxic gases. Runoff from fire control or dilution water may be corrosive and/or toxic and cause pollution.

Fire Hazard

Combustible material: may burn but does not ignite readily. When heated, vapors may form explosive mixtures with air: indoors, outdoors and sewers explosion hazards. Contact with metals may evolve flammable hydrogen gas. Containers may explode when heated. Runoff may pollute waterways. Substance may be transported in a molten form.
