[The detection of the 25B-NBOMe derivative of phenylethylamine in the biological material].

This article is focused on the conditions for the detection and identification of 2-[4-bromo-2.5-dimethoxyl]-N-[(2-methoxyphenyl)methyl] ethamine (25B-NBOMe) and its major metabolites by the combination of the HPLC/MS/MS techniques. The high-resolution mass spectra obtained with the use of a linear ion trap are described. The results of the study give evidence of the possibility for the detection of the analytes within 24 hours after drug consumption and within 3 months after the storage of the biological material of interest in a refrigerator at a temperature of 3-5 °C. The data obtained confirmed high stability of 2-(4-bromo-2.5-dimethoxyl]-N-[(2-methoxyphenyl)methyl] ethamine and its metabolites in the biological tissues.
