N-Piperidinyl Etonitazene is classified as a novel opioid. A novel opioid is a Novel Psychoactive Substance (NPS) with one NPS arriving on the market each week. These are chemicals made in a laboratory (usually in China) and shipped to the United States for consumption.
Structurally similar compounds include etonitazene, metonitazene, and isotonitazene. N-piperidinyl Etonitazene is a chemical compound that was created in the 1950s by researchers at Pfizer. Data suggest that this group of analogues can have potency similar to or greater than fentanyl.
Recent in vitro data suggest that N-piperidinyl etonitazene is slightly less potent than etonitazene but more potent than fentanyl (unpublished data from M. Vandeputte and C. Stove). N-Piperidinyl Etonitazene is not explicitly scheduled in the United States; however, etonitazene and isotonitazene are Schedule I substances.
N-Piperidinyl Etonitazene will usually appear as a crystalline powder.
