25N-NBOMe

Also known as 2C-N-NBOMe · 25N

25N-NBOMe is the N-(2-methoxybenzyl) derivative of 2C-N, bearing a 4-nitro group on the phenethylamine ring. It is a potent 5-HT2A agonist psychedelic of the NBOMe class, orally inactive and sub-milligram active, with the same narrow safety margin, vasoconstriction and seizure hazards.

01 Overview

25N-NBOMe is a rare member of the 25x-NBOMe series distinguished by its 4-nitro ring substituent. It has appeared occasionally on blotter research-chemical markets and in seized samples.

There are essentially no controlled human data; information is anecdotal and forensic. The nitro substitution and NBOMe modification give a potent, long-acting psychedelic that shares the class hazards, and the compound has been implicated in acute toxicity presentations.

02 Mechanism

Potent agonist at serotonin 5-HT2A receptors; N-2-methoxybenzyl substitution of 2C-N sharply increases 5-HT2A affinity relative to the parent.
