Methoxphenidine also known as MXP is found in the family of diarylethylamine research chemical.
There is not enough data available on methoxphenidine as a supplementary chemical for any medical use at this time and therefore it is not intended for human consumption. Manufacturers use synthetic substances to create analogs of medications that are listed as controlled substances to further help scientists perform experiments on similar research chemicals with the hopes of finding alternative compounds that will benefit humans with harsh or long term side effects.

The chemistry of methoxphenidine shows that it has a phenethylamine skeleton substituted along with at Ra an extra phenyl ring. The end amino group is incorporated into a peperidine ring with a phenethylamine chain. This makes methoxphenidine a peperidine dissociative and is an analog of diphenidine structurally with an extra 2-methoxy CH30 substitute.

When looking at the pharmacology of MXP it blocks the NMDA receptors while disconnecting the neurons that will produce effects such as having problems moving and loss of feeling, which may after more research is conducted by used as an anesthetic. However, all of the data is only due to its relationship to other dissociatives and more data needs to be compiled before the research chemical can be used in clinical trials. The long-term effects, toxicity, and abuse potential are unknown at this time.
