RESEARCH OF SYNTHETIC CANNABINOID UR-144

Abstract

The purpose on the basis of a complex analysis of theoretical information and the results of experimental study
of UR-144, develop an optimal scheme for the study of this substance, which is necessary for obtaining reliable results
and forming a well-founded and objective conclusion of a forensic expert. Methodology. To achieve the scientific goal,
a complex of general scientific and special research methods was applied. Using analytical, generalizing approaches,
theoretical data on the solved issue were systematized. The application of various methods of analysis made it possible
to summarize the results of the study and propose an analysis scheme. The reliability of the obtained results is provided by modern physico-chemical methods of analysis and the possibilities of program interpretation of the obtained results. Scientific novelty. An optimal scheme for the study of substances containing UR-144 was developed, which is based on the identification of the substance and the determination of its quantitative content. For the identification of UR-144, it is proposed to use qualitative chemical reactions, thin-layer chromatography and a modern instrumental method – mass-selective detection with direct input. Conclusions. The qualitative determination of UR-144 was carried out by the methods of qualitative chemical reactions and thin-layer chromatography, the sensitivity and selectivity of which were confirmed by the results of tested instrumental research methods. The following instrumental research methods are proposed for the identification of UR-144: IR spectroscopy and mass-selective detection with direct input. The features of identification of UR-144 in the studied objects by the method of gas chromatography with the use of mass-selective and flame-ionization detection are characterized. A generalized scheme of the UR-144 study has been developed, which can be used to prepare a scientifically based opinion of a forensic expert.
