Morphinone is an opioid that is the intermediate when morphine is being converted to hydromorphone (trade name Dilaudid).1

Chemical structure

Morphinone can be described as the ketone of morphine.

Morphinone itself is an active opioid, though its potency is closer to codeine than morphine. It is, however, an important precursor and would fall under the purview of the Controlled Substances Act within the United States. Its legal status in other countries varies.
