O-Nitroanisole

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:
 * NaOCH3 +  ClC6H4NO2  →   CH3OC6H4NO2  +  NaCl

The resulting 2-chloronitrobenzene can be reduced to o-anisidine, which is a precursor to dyes.
