25C-NBOMe--new potent hallucinogenic substance identified on the drug market.

Forensic Science International April 10, 2013 Dariusz Zuba, Karolina Sekuła, Agnieszka Buczek 128 citations

A new hallucinogenic substance, 25C-NBOMe, was identified in blotter papers seized from the drug market using multiple analytical methods. Gas chromatography-mass spectrometry (GC-MS) showed a spectrum similar to other 25-NBOMe compounds, with dominant ions at m/z=150, 121, and 91. Derivatization helped determine the molecular mass, and liquid chromatography-quadrupole time-of-flight mass spectrometry (LC-QTOF-MS) confirmed the exact molecular mass and chemical formula. MS/MS experiments showed the substance is an N-(2-methoxy)benzyl derivative of 2C-C. Fourier-transform infrared spectroscopy (FTIR) corroborated the identity, and nuclear magnetic resonance (NMR) spectroscopy provided final structural elucidation.

Identification and characterization of 2,5-dimethoxy-4-nitro-β-phenethylamine (2C-N)--a new member of 2C-series of designer drug.

Forensic Science International October 10, 2012 Dariusz Zuba, Karolina Sekuła, Agnieszka Buczek 26 citations

A powder sample seized by Polish authorities in 2011 was identified as the hallucinogen 2,5-dimethoxy-4-nitro-β-phenethylamine (2C-N). Mass spectrometry confirmed its molecular mass, and gas chromatography and liquid chromatography produced characteristic ion patterns. Infrared spectroscopy showed two broad bands from the nitro group, and nuclear magnetic resonance spectroscopy unequivocally determined the molecular structure. The analytical approach proved effective for characterizing new designer drugs.
