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. Chlorination of 2-nitrotoluene gives two isomers of the chloronitrotoluenes. Similarly nitration gives two isomers of dinitrotoluene. 2-Nitrotoluene is mainly consumed in the production of o-toluidine, a precursor to dyes.Gerald Booth Nitro Compounds, Aromatic 2007 10.1002/14356007.a17_411 References External links CDC - NIOSH Pocket Guide to Chemical Hazards - o-Nitrotoluene Category:Nitrotoluenes Category:2-Tolyl compounds Category:IARC Group 2A carcinogens
