1. A chemical compound formed by the substitution of two nitro groups (-NO₂) into a benzene ring; exists in three isomeric forms (ortho, meta, and para) and is used in the manufacture of dyes, explosives, and other organic compounds.
Usage: chemistry; technical term; typically used in plural or with isomer designation (e.g., 1,4-dinitrobenzene)

Examples

• Dinitrobenzene is an important intermediate in the synthesis of aniline dyes.
• The para isomer of dinitrobenzene is the most commonly produced form.
• Dinitrobenzene compounds are used in the manufacture of explosives and propellants.
• The three isomers of dinitrobenzene have different physical and chemical properties.
• Industrial production of dinitrobenzene involves the nitration of nitrobenzene.
