3-Nitrotoluene or '''meta-nitrotoluene' is an organic compound with the formula . It is one of three isomers of nitrotoluene. A yellow liquid, it is used in the manufacture of meta''-toluidine, which is an intermediate in the production of various dyes.
==Synthesis and reactions== It is made by nitrating toluene by conventional mixed acid (acetyl nitrate doesn't produce it): this reaction mainly affords a 2:1 mixture of 2-nitro and 4-nitro isomers, but after removal of the 2-isomer, the 3-nitrotoluene can be purified by distillation. It is a precursor to toluidine, which is used in producing azo dyes.
