A chemical compound made by combining toluene with nitro groups, commonly used in explosives and as a chemical intermediate in manufacturing.
From di- (two) + nitro- (nitrogen-oxygen compounds) + toluene (a hydrocarbon from tolu balsam). The term emerged in 19th-century chemistry as scientists systematically named organic compounds by their structure.
Dinitrotoluene is a precursor to TNT (trinitrotoluene) and was heavily produced during both world wars—understanding this compound is key to understanding 20th-century military chemistry. Its industrial importance led to major chemical plants and entire industries built around its manufacture.
