General description
1,2-Dinitrobenzene belongs to the class of nitroaromatic compounds, which are utilized for the manufacture of pesticides, explosives, polymers, etc. They can pose a potential risk to the environment because of their toxic nature.
Application
1,2-Dinitrobenzene has been used as an analytical standard for the determination of the analyte in organic explosives investigated during the forensic analysis by liquid chromatography-atmospheric pressure chemical ionization mass spectrometry (LC-APCI-MS). It may be used as an analytical standard for the determination of the analyte in aqueous samples, environmental samples and human biological samples by various chromatographic techniques.
Refer to the product′s Certificate of Analysis for more information on a suitable instrument technique. Contact Technical Service for further support.

Hazardous waste site characterization, forensic investigations, and land mine detection are scenarios where soils may be collected and analyzed for traces of nitroaromatic, nitramine, and nitrate ester explosives. These thermally labile analytes are traditionally determined by high-performance liquid chromatography (HPLC);
