3-Nitrotoluene or meta-nitrotoluene is an organic compound with the formula Шаблон:Chem2. 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.[1]

Synthesis and reactions

It is made by nitrating toluene. 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.[1]
