What the agency says
The Drug Enforcement Administration (DEA) issues this temporary order to schedule 1-(1-(1-(4-bromophenyl)ethyl)piperidin-4- yl)-5,6-dichloro-1,3-dihydro-2H-benzo[d]imidazol-2-one (commonly known as 5,6-dichloro brorphine or SR-14968); 5,6-dichloro-1-(1-(4- chlorobenzyl)piperidin-4-yl)-1,3-dihydro-2H-benzo[d]imidazol-2-one (commonly known as 5,6-dichloro desmethylchlorphine or SR-17018); 3-(3- (1-(1-(4-chlorophenyl)ethyl)piperidin-4-yl)-2-oxo-2,3-dihydro-1H- benzo[d]imidazol-1-yl)propanenitrile (commonly known as N-propionitrile chlorphine or cychlorphine); and 8-(1-(4-chlorophenyl)ethyl)-1-phenyl- 1,3,8-triazaspiro[4.5]decan-4-one (commonly known as spirochlorphine or R-6890), including their isomers, esters, ethers, salts, and salts of isomers, esters, and ethers, whenever the existence of such isomers, esters, ethers, and salts is possible, to schedule I under the Controlled Substances Act. DEA bases this action on a finding that placing 5,6-dichloro brorphine, 5,6-dichloro desmethylchlorphine, N- propionitrile chlorphine, and spirochlorphine in schedule I is necessary to avoid an imminent hazard to public safety. This order imposes the regulatory controls and administrative, civil, and criminal sanctions applicable to schedule I controlled substances on persons who handle (manufacture, distribute, reverse distribute, import, export, engage in research, conduct instructional activities or chemical analysis, or possess) or propose to handle these substances.
