The invention relates to heterocyclic compounds, in particular to the use of 5-Chloro-4,6-dshtprobenzofurazan as a reagent for the manifestation of spots in thin-layer chromatography of aromatic amines 5-chlorobin-dinctrobenzofurazan in acetonitrile allows by staining stained spots, carry out the qualitative identification of pepper aromatic amines in the presence of secondary and tertiary, as well as in a number of cases, detect isomeric and substituted 5-chloro-4,6-dinitrobenzofura- nane compounds by nitration of 5-chloro-6-nitro benzofurazan. 1 tab. i |
