[Determination of 2,4,6-trinitromethylbenzene in biological material].

The objective of this study was to search for the optimal conditions necessary to extract 2,4,6-trinitromethylbenzene (2,4,6-TNMB) from biological material with acetonitrile. It is shown that 2,4,6-TNMB can be purified from the coextracted components of the biological material on a silica gel column, L 40/100 mcm. Methods are described for the identification and quantitative measurement of 2,4,6-trinitromethylbenzene in the cadaveric liver tissue by thin layer paper chromatography, IR spectrophotometry, and reverse phase high-performance liquid chromatography (rp-HPLC) with the use of a diode-matrix detector.
