Dinitrobenzene, with molecular formula C6H4(NO2)2, is a colorless, crystalline, flammable and explosive solid compound. It is mainly used for producing nitroaromatic compounds.

Dinitrobenzene can be produced by nitrating benzene with a mixture of nitric and sulfuric acids. It can also be synthesized from benzenediazonium salts under certain conditions.

The main use of dinitrobenzene is in the production of nitroaromatic compounds. It can also be reacted with an alkyl halide to produce alkyl nitroaromatics. It is also used as a fungicide and an intermediate in the synthesis of dyes, explosives and other organic compounds.

Dinitrobenzene is also used to test for the presence of aldehydes. It behaves like an aldehyde when heated with cuprous chloride. When heated in the presence of hydroxylamine-sulfuric acid, dinitrobenzene gives a violet color in the presence of an aldehyde.

It can be hazardous if inhaled, ingested or absorbed through the skin. It should be handled with care and kept away from sources of ignition. Proper safety equipment and protective clothing should be worn when handling this chemical.
