Drug Enforcement Administration October 12, 2023 – Federal Register Recent Federal Regulation Documents

The Drug Enforcement Administration finds that propionyl chloride is used in the illicit manufacture of the controlled substance fentanyl, as well as fentanyl analogues, and fentanyl-related substances and is important to the manufacture of these substances because it is often used in synthetic pathways to illicitly manufacture fentanyl, fentanyl analogues, and fentanyl-related substances. Prior to proposing to list propionyl chloride as a list I chemical, DEA is soliciting information on the current uses of propionyl chloride (other than for the synthesis of fentanyl) in order to properly determine the effect such a proposed action would have on legitimate industry.
