Potential of chromatography and mass spectrometry for the differentiation of three series of positional isomers of 2‐(dimethoxyphenyl)‐ N ‐(2‐halogenobenzyl)ethanamines
Autor: Olga Kupriyanova, Vadim Shevyrin, Yuri M. Shafran
Publikováno v: Drug Testing and Analysis. 14:1102-1115
N-(2-substituted benzyl)-2,5-dimethoxyphenethylamines often cause severe poisonings which has led to their legal prohibition in many countries. At the same time, their positional isomers can be studied as potential therapeutic drugs. In this regard,
