General description

2,4-Dinitrotoluene is classified under the group of nitroaromatic compounds, which are organic nitro derivatives of analytical research interest. It finds wide use as a precursor of 2,4,6-trinitrotoluene (TNT) explosive as well as dyes and urethane products. 2,4-Dinitrotoluene is regarded as a potential threat to human health even when present in trace amounts.
This compound is listed in the SVHC (Substances of very high concern) candidate list of ECHA (European Chemicals Agency)

Application

2,4-Dinitrotoluene may be used as an analytical standard for the determination of the analyte in forensic samples, explosive-contaminated groundwater samples, industrial effluents and seawater 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.

This paper compares solid-phase microextraction (SPME) with a recently developed extraction method called single-drop microextraction (SDME) for the analysis of nitroaromatic explosives in water samples. The two techniques are examined in terms of procedure, chromatographic analysis and method performance. All
