Identification and characterization of 2,5-dimethoxy-3,4-dimethyl-β-phenethylamine (2C-G) - A new designer drug

摘要: This study presents and discusses the mass spectrometric, infrared spectroscopic nuclear magnetic resonance data of 2,5-dimethoxy-3,4-dimethyl-β-phenethylamine (2C-G), a new designer drug. A powder sample containing 2C-G was seized in Poland 2011. The paper focuses on comparison analytical features other members 2C-series, order to assess possibility unequivocal identification. occurrence intense peak at m/z = 178 different intensities ions 165 180 gas chromatography-electron impact-mass spectrometry (GC-EI/MS) spectrum made it possible distinguish from 2C-E. Differences relative 192, 179 177 were observed for GC-EI/MS spectra TFAA derivatives An identical set recorded these substances using liquid chromatography-electrospray ionization/quadrupole time flight (LC-ESI/QTOFMS) method both MS tandem (MS/MS) mode, but distinction based differences ion 193.1223 178.0988. Fourier transform (FTIR) significantly with characteristic doublets 993-1014 cm(-1) 1099-1124 , ratio bands higher wavenumbers. Final elucidation structure carried out by (1) H (13) C NMR spectroscopy. indicated that marketing analogues controlled poses real challenge forensic laboratories, application sophisticated methods is often required identification substance.
