2-Chloro-4-nitroaniline Usage And Synthesis
  • Chemical Propertiesyellow crystalline powder
  • UsesIntermediate in manufacture of dyes.
  • Synthesis Reference(s)The Journal of Organic Chemistry, 51, p. 5039, 1986 DOI: 10.1021/jo00375a062
  • General DescriptionYellow crystalline powder.
  • Air & Water ReactionsInsoluble in water.
  • Reactivity Profile2-Chloro-4-nitroaniline can react with oxidizing materials.
  • HazardToxic by ingestion and inhalation.
  • Health HazardTOXIC; 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 HazardCombustible 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.
