[The determination of toxic compounds with a dinitrophenol structure in the forensic chemical study of cadaveric material].

A method for forensic chemical assessment of dinitrophenol toxic compounds has been developed. Acetone was used as the isolating agent. The isolates were purified by extraction followed by adsorption in a column packed with silica gel. The analyzed substances are analyzed by chromogenic reactions, from UV and visible spectra in alkali and DMPA, and by thin-layer and high-pressure chromatography. The method allows the detection of 47-83% dinitrophenols in artificial mixtures with liver tissue (with 50 mg of analyzed substance per 100 g of the object). The detection minimum for this group of compounds is 0.5 to 1.0 mg per 100 g of cadaveric material.
