What does nitrobenzene mean?
Nitrobenzene is a pale-yellow aromatic chemical compound with the formula C6H5NO2. Structurally, it consists of a benzene ring bearing one nitro group, and it is produced industrially through the nitration of benzene. The substance is toxic, harmful to the environment, and classified as a human carcinogen, so its manufacture, handling, and disposal require strict safety controls. Historically and commercially, nitrobenzene has served mainly as an intermediate in chemical synthesis, including the production of other industrial compounds. In laboratory and environmental contexts, the word denotes both the substance itself and traces or contamination associated with it. Its name directly reflects its chemical composition: the prefix nitro- identifies the attached nitro group, while benzene identifies the aromatic parent compound.
nounA toxic, pale-yellow aromatic liquid with the molecular formula C6H5NO2, formed by replacing one hydrogen atom in benzene with a nitro group. It is used as a chemical intermediate and is classified as a carcinogen.
- The chemical compound C6H5NO2, also known as phenyl nitrate.
"The laboratory treated the contaminated surface with precautions because traces of nitrobenzene were detected."
"Nitrobenzene is produced industrially by the nitration of benzene."
"The waste facility was fined after releasing nitrobenzene into the surrounding groundwater."
Nitrobenzene is benzene with one crucial chemical addition: a nitro group that turns a familiar solvent into a toxic, carcinogenic substance.

Where does nitrobenzene come from?
Nitrobenzene is a compound name formed from nitro- and benzene. The element benzene was named from the German word Benzol, itself associated with benzoe, an aromatic resin. The nitro- element comes through French and ultimately from the Latin nitrum, meaning natron, a naturally occurring sodium carbonate compound.
How nitrobenzene is actually used
Nitrobenzene is primarily a technical term used in chemistry, toxicology, environmental science, and industrial safety. It normally refers to the specific compound rather than to the broader class of nitro-substituted aromatic compounds.
Easily confused with nitrobenzene
Benzene is the parent aromatic compound C6H6, whereas nitrobenzene is a distinct compound containing a nitro group.
