Application

1,2-Dinitrobenzene was used as internal standard for analysis of the explosives, TNT, RDX, and tetryl in sea water by vapor phase chromatography with the nickel-63 electron capture detector.

General description

The electrochemistry of 1,2-dinitrobenzene in the presence of 1,3-diphenylurea was studied. The kinetics of the aromatic nucleophilic substitution reactions of 1,2-dinitrobenzene with butylamine and piperidine were investigated as a function of the amine concentration and temperature.

[reaction: see text] The electrochemistry of 1,2-dinitrobenzene (1,2-DNB), 1,3-dinitrobenzene (1,3-DNB), and 1,4-dinitrobenzene (1,4-DNB) is strongly affected by the presence of 1,3-diphenylurea. In DMF, the second reduction potential of all three DNBs shifts substantially positive in the presence of the urea

3,4-Dinitrobiphenyl derivatives were mutagenic in Salmonella typhimurium TA98, TA98/1,8-DNP6 and in TA98NR. We describe here the specific reactivity of 3,4-dinitrobiphenyl derivatives with diluted sodium hydroxide solution and the determination of the amounts of released nitrous ion. 3,4-Dinitrobiphenyl derivatives begin to

Conditions have been examined for the use of o-dinitrobenzene as a substrate for colorimetric assay of glutathione S-transferases. Activities can be determined by measuring nitrite released enzymatically from the substrate using a diazo-coupling method with N-(1-naphthyl)ethylenediamine dihydrochloride and sulfanilamide. The
