Description and Uses

2,4-Dinitrotoluene is the most common of the six dinitrotoluene isomers. Dinitrotoluene (DNT) or Dinitro is an explosive with the formula C6H3(CH3)(NO2)2. At room temperature it is a pale yellow to orange crystalline solid. It is a high explosive and one of the precursors for trinitrotoluene (TNT), which is synthesized through three separate nitrations of toluene. The first product is mononitrotoluene, DNT is the second, and TNT is the third and final product. Dinitrotoluene induced sensitization in an employee of a manufacturers of explosives, also sensitized to nitroglycerin.

A metabolite of TNT (2,4,6-trinitrotoluene). The metabolites of TNT
