Noroxymorphone

Noroxymorphone is an opioid which is both a metabolite of oxymorphone and is manufactured specifically as an intermediate in the production of narcotic antagonists such as naltrexone and others.

In the United States, noroxymorphone is controlled as a Schedule II Narcotic controlled substance with an ACSCN of 9637 and in 2014 the DEA set annual aggregate manufacturing quotas of 17 500 kilogrammes for conversion and 1262.5 kg for sale. In other countries, it may be similarly controlled, controlled at a lower level, or regulated in another way.
