p-Anisidine (or para-anisidine) is an organic compound with the formula CH 3 OC 6 H 4 NH 2. A white solid, commercial samples can appear grey-brown owing to air oxidation. It is one of three isomers of anisidine, methoxy-containing anilines. It is prepared by reduction of 4-nitroanisole. [8]

NaOCH 3 + ClC 6 H 4 NO 2 → CH 3 OC 6 H 4 NO 2 + NaCl. The resulting o-nitroanisole is reduced to o-anisidine. o-Anisidine is used in the manufacture of dyes. It is nitrated to give 4-nitroanisidine. It is also a precursor to o-dianisidine. One special use is as a heartwood indicator. An acid solution of o-anisidine is diazotized by adding a ...
Anisidine can refer to any of the three possible isomers of methoxyaniline: o-Anisidine (2-methoxyaniline) m-Anisidine (3-methoxyaniline) p-Anisidine (4-methoxyaniline), used in measuring anisidine value
