4-HO-MET (Metocin) Analytical Specs & Buying Guide

Analytical laboratories and research institutions looking to buy 4-HO-MET (4-hydroxy-N-methyl-N-ethyltryptamine, commonly known as Metocin) require reliable analytical reference standards with verified purity profiles.

As a synthetic substituted tryptamine, 4-HO-MET is widely utilized in forensic spectroscopy, receptor binding assays, and chromatographic identification. Finding verified 4-HO-MET for sale with certified analytical documentation ensures high reproducibility across mass spectrometry (LC-MS/MS) and nuclear magnetic resonance (NMR) workflows.

4-HO-MET Chemical Profile & Structural Identity

4-HO-MET (CAS Number: 77872-41-4) is a homologue of 4-HO-DMT (Psilocin), characterized by the substitution of an N-methyl-N-ethyl group on the tryptamine side chain. Due to its structural relationship with naturally occurring tryptamines, certified reference materials are critical for resolving chromatographic overlaps in forensic screening.
