mononitrotoluene

Mononitrotoluene or nitrotoluene (MNT or NT), is any of three organic compounds with the formula C6H4(CH3)(NO2). They can be viewed as nitro derivatives of toluene or as methylated derivatives of nitrobenzene.

Mononitrotoluene comes in four isomers, differing by the relative position of the methyl and nitro groups. All are pale yellow with faint fragrances: ortho-nitrotoluene (also called ONT, o-nitrotoluene, or 2-nitrotoluene). m.p. = −10.4 °C meta-nitrotoluene (MNT, m-nitrotoluene, or 3-nitrotoluene). m.p. = 16 °C para-nitrotoluene (PNT, p-nitrotoluene, or 4-nitrotoluene). m.p. = 51 °C , in which the benzylic carbon is nitrated. m.p. = 80.7 °C.
