o-Nitroanisole is an organic compound with the formula CH3OC6H4NO2. Three isomers of nitroanisole exist, but the o-isomer is the most commercially important. It is a colorless liquid.
It is prepared by treatment of o-chloronitrobenzene with sodium methoxide:{{cite encyclopedia|author=Gerald Booth|title=Nitro Compounds, Aromatic|encyclopedia=Ullmann's Encyclopedia of Industrial Chemistry|year=2007|publisher=Wiley-VCH|location=Weinheim|doi=10.1002/14356007.a17_411|isbn=978-3527306732}}
:NaOCH3 + ClC6H4NO2 → CH3OC6H4NO2 + NaCl
The resulting 2-chloronitrobenzene can be reduced to o-anisidine, which is a precursor to dyes.
