The three possible arrangements of the nitro groups afford three isomers, 1,2-dinitrobenzene, 1,3-dinitrobenzene, and 1,4-dinitrobenzene. Each isomer has the chemical formula C 6 H 4 N 2 O 4 and a molar mass of about 168.11 g/mol. 1,3-Dinitrobenzene is the most common isomer and it is used in the manufacture of explosives.
They have the formula C 6 H 6–n (NO 2) n, where n = 1–6 is the number of nitro groups. Depending on the number of nitro groups, there may be several constitutional isomers possible. Mononitrobenzene; Dinitrobenzene. 1,2-Dinitrobenzene; 1,3-Dinitrobenzene; 1,4-Dinitrobenzene; Trinitrobenzene. 1,2,3-Trinitrobenzene; 1,2,4-Trinitrobenzene; 1,3 ...
1,4-Dinitrobenzene is one of three isomers of dinitrobenzene, with the formula C 6 H 4 (NO 2) 2. The 1,4-isomer is most symmetrical. The compound is a yellow solid that is soluble in organic solvents. It is prepared from 4-nitroaniline by diazotization followed by treatment with sodium nitrite in the presence of a copper catalyst.

1,2-Dinitrobenzene is one of three isomers of dinitrobenzene, with the formula C 6 H 4 (NO 2) 2. The compound is a white or colorless solid that is soluble in organic solvents. It is prepared from 2-nitroaniline by diazotization and treatment with sodium nitrite in the presence of a copper catalyst. [1]
1-Fluoro-2,4-dinitrobenzene (commonly called Sanger's reagent, dinitrofluorobenzene, DNFB or FDNB) is a chemical that reacts with the N-terminal amino acid of polypeptides. This can be helpful for sequencing proteins .
Description: Space-filling model of a 1,4-dinitrobenzene molecule, C 6 H 4 N 2 O 4, also known as para-dinitrobenzene or p-dinitrobenzene.The molecule is shown as found in the crystal structure reported in Phys. Chem. Chem. Phys. (2018) 20, 24192–24200 and CSD entry DNITBZ13.
