Schedules of Controlled Substances: Temporary Placement of Butyryl Fentanyl and Beta-Hydroxythiofentanyl Into Schedule I

The Administrator of the Drug Enforcement Administration is issuing this notice of intent to temporarily schedule the synthetic opioids, N-(1-phenethylpiperidin-4-yl)-N-phenylbutyramide (butyryl fentanyl) and N-[1-[2-hydroxy-2-(thiophen-2-yl)ethyl]piperidin-4-yl]-N- phenylpropionamide (beta-hydroxythiofentanyl), into schedule I pursuant to the temporary scheduling provisions of the Controlled Substances Act. This action is based on a finding by the Administrator that the placement of these synthetic opioids into schedule I of the Controlled Substances Act is necessary to avoid an imminent hazard to the public safety. Any final order will impose the administrative, civil, and criminal sanctions and regulatory controls applicable to schedule I controlled substances under the Controlled Substances Act on the manufacture, distribution, possession, importation, and exportation of, and research and conduct with, instructional activities of these synthetic opioids.
