Oxymorphazone was first synthesised in 1979 by a team of Chemists at Rockefeller University, New York. Recent attempts to build effective irreversible opioid agonists encouraged the team to develop a hydrazone derivative of oxymorphone.
Oxymorphazone is an opioid of the morphinan class. Oxymorphazone and other molecules of this class contain a polycyclic core of three benzene rings fused in a zig-zag pattern called phenanthrene. A fourth nitrogen containing ring is fused to the phenanthrene at R9 and R13 with the nitrogen member looking at R17 of the combined structure. This structure is called morphinan. Oxymorphazone is structurally similar to Oxymorphone, with a C6 substitution of oxygen with a hydrazone group.
Disclaimer: The effects listed below cite the Subjective Effect Index (SEI), an open research literature based on anecdotal user reports and the personal analyses of PsychonautWikicontributors. As a result, they should be viewed with a healthy degree of skepticism.
It is also worth noting that these effects will not necessarily occur in a predictable or reliable manner, although higher doses are more liable to induce the full spectrum of effects. Likewise, adverse effects become increasingly likely with higher doses and may include addiction, severe injury, or death ☠.

This toxicity and harm potential section is a stub.
As a result, it may contain incomplete or even dangerously wrong information! You can help by expanding upon or correcting it. Note: Always conduct independent research and use harm reduction practices if using this substance.
Warning:Many psychoactive substances that are reasonably safe to use on their own can suddenly become dangerous and even life-threatening when combined with certain other substances. The following list provides some known dangerous interactions (although it is not guaranteed to include all of them).
Always conduct independent research (e.g. Google, DuckDuckGo, PubMed) to ensure that a combination of two or more substances is safe to consume. Some of the listed interactions have been sourced from TripSit.
