1,3-Dinitrobenzene is one of three isomers of dinitrobenzene, with the formula C6H4(NO2)2. It is one of three isomers of dinitrobenzene. The compound is a yellow solid that is soluble in organic solvents.
== Preparation == 1,3-Dinitrobenzene is accessible by nitration of nitrobenzene. The reaction proceeds under acid catalysis using sulfuric acid. The directing effect of the nitro group of nitrobenzene leads to 93% of the product resulting from nitration at the meta-position. The ortho- and para-products occur in only 6% and 1%, respectively. 400px|Nitration of nitrobenzene to produce dinitrobenzenes
