|Section2= |Section7= |Section8= }} 4-Nitroaniline, p-nitroaniline or 1-amino-4-nitrobenzene is an organic compound with the formula C6H6N2O2. It is an organic chemical compound, consisting of a phenyl group attached to an amino group which is para to a nitro group. 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. == Synthesis == It is produced industrially via the amination of 4-nitrochlorobenzene:〔Gerald Booth "Nitro Compounds, Aromatic'' in Ullmann's Encyclopedia of Industrial Chemistry, 7th Ed.; Wiley-VCH: Weinheim, 2005. 〕 :ClC6H4NO2 + 2 NH3 → H2NC6H4NO2 + NH4Cl Below is a laboratory synthesis of 4-nitroaniline from aniline. The key step in this reaction sequence is an electrophilic aromatic substitution to install the nitro group ''para'' to the amino group. After this reaction, a separation must be performed to remove 2-nitroaniline, which is also formed in a small amount during the reaction.〔(Mohrig, J.R.; Morrill, T.C.; Hammond, C.N.; Neckers, D.C.
