Uses of 4-Nitroaniline. This chemical is commonly used as an intermediate in the synthesis of dyes, antioxidants, pharmaceuticals and gasoline, in gum inhibitors, poultry medicines, and as a corrosion inhibitor. What's more, it can be used to produce 1-(4-nitro-phenyl)-pyrrole-2-carbaldehyde by reaction with furfural. The reaction occurs with reagent 2n-HCl and solution ethanol with other condition of heating for 2 hours. The yield is about 90%.
