In chemistry, the dinitrotoluenes (also dinitrotoluenes ) form a group of aromatic compounds that are derived from both toluene and dinitrobenzenes . The structure consists of a benzene ring with an attached methyl group (-CH 3 ) and two nitro groups (-NO 2 ) as substituents . Their different arrangement results in six constitutional isomers with the empirical formula C 7 H 6 N 2 O4 , with 2,4-dinitrotoluene being the best known.
