2-Nitrotoluene or '''ortho-nitrotoluene''' is an organic compound with the formula CH3C6H4NO2. It is pale yellow liquid that crystallizes in two forms, called α (−9.27 °C) and β (−3.17 °C). It is mainly a precursor to o-toluidine, which is an intermediate in the production of various dyes.
==Synthesis and reactions== It is made by nitrating toluene at above −10 °C. This reaction affords a 2:1 mixture of 2-nitro and 4-nitro isomers.
