Résumé:

This paper reports on the identification and full chemical characterization of the substance colloquially called “etonitazepyne” or “N-pyrrolidino etonitazene” (2-(4-ethoxybenzyl)-5-nitro-1-(2-(pyrrolidin-1-yl)ethyl)-1H-benzo[d]imidazole), a potent NPS opioid of the 5-nitrobenzimidazole class.
