[Determination of 2.4-dinitrophenol, its basic metabolite and 4-oxide diphenyl in biological materials].

A possibility was considered to isolate, by using dimethylformamide, 2.4-dinitrophenol, 2-amino-4-nitrophenol and 4-oxid-diphenyl from a biological-origin object. A method of extraction with subsequent chromatography in thin silicon-gel layer was used to purify the isolates from biological materials. The designed technique provides for identifying and for quantitatively defining the discussed phenol structures contained in the isolates from the liver tissue of corpses and human blood.
