| 4-Methyl-3-nitroaniline Usage And Synthesis |
Description | 4-Methyl-3-nitroaniline is one of the intermediates or products in the photochemical transformations (λ=254 nm) of 2,4-dinitrotoluene (2,4-DNT) in aqueous solutions containing the cationic surfactant cetyltrimethylammonium (CTA) and the anionic nucleophile borohydride (BH4-)[1]. | Chemical Properties | Orange Crystalline Solid | Uses | 4-Methyl-3-nitroaniline is a compound useful in organic synthesis. It is used to make pigments and dyes. It could also be used in Environmental Testing. It could be used as raw material to synthesized N-(4-methyl-3-nitrophenyl)-4-(4-methylpiperazin-1-ylmethyl)benzamide through acylation[2]. | Definition | ChEBI: 4-Amino-2-nitrotoluene is a C-nitro compound. | Synthesis Reference(s) | Tetrahedron Letters, 30, p. 251, 1989 DOI: 10.1016/S0040-4039(00)95173-6 | Reactivity Profile | 4-Methyl-3-nitroaniline is incompatible with acids, acid chlorides, acid
anhydrides, chloroformates and strong oxidizing agents (NTP, 1992). | Hazard | Toxic by ingestion. | Fire Hazard | Excerpt from ERG Guide 153 [Substances - Toxic and/or Corrosive
(Combustible)]: Combustible material: may burn but does not ignite
readily. When heated, vapors may form explosive mixtures with air:
indoors, outdoors and sewers explosion hazards. Those substances
designated with a (P) may polymerize explosively when heated or involved
in a fire. 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. (ERG, 2020) | Safety Profile | Poison by ingestion andintravenous routes. Combustible when exposed to heat orflame. To fight fire, use CO2, spray, foam. When heated todecomposition it emits toxic fumes of NOx. | Purification Methods | Crystallise the aniline from hot water (charcoal), then ethanol and dry it in a vacuum desiccator.
