EVERYTHING YOU NEED TO KNOW ABOUT METHOXPHENIDINE: THE ULTIMATE GUIDE FOR CANADIAN RESEARCHERS

What if a single aryl-cyclohexylamine could block NMDA receptors with 10x the potency of ketamine—yet remain unscheduled in most jurisdictions? As a Canadian researcher probing dissociative anesthesia, neuroprotection, or glutamate signaling, methoxphenidine (MXP) delivers precision without regulatory hurdles. However, its long duration and unknown metabolites demand rigorous protocols. This guide explores its chemistry, applications, and compliant sourcing from ChemLabs Canada—all grounded in peer-reviewed data.

WHAT IS METHOXPHENIDINE?

Methoxphenidine (2-MeO-Diphenidine, MXP) is a dissociative research chemical from the diarylethylamine class. Its chemical formula is C₂₀H₂₅NO,** and it acts as a potent NMDA receptor antagonist. In labs, it induces dissociation, analgesia, and amnesia to model schizophrenia or stroke. For example, neuroscientists use it to study excitotoxicity without ketamine’s rapid clearance.

Chemical Structure Breakdown

Methoxphenidine features a diphenylmethyl-piperidine core with a 2-methoxyphenyl substituent. The methoxy group enhances lipophilicity (logP ≈ 4.2) and BBB penetration.

Common Synonyms

Known as MXP, 2-MXP, or 2-MeO-Diphenidine (CAS 127529-46-8). Specify HCl salt for solubility.

Role in Research

Serves as long-acting dissociative in binding assays and neuroprotection studies. Requires CCAC approval for in vivo use.

HISTORY OF METHOXPHENIDINE

First synthesized in 1989 by Parsons at Merck, methoxphenidine emerged online in 2013. Its slow onset and extended effects fueled research interest.

Early Discovery

Patented as NMDA antagonist for stroke. However, development halted due to duration concerns.
