Description

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.[1]

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).[2] 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.[3][4]
