Buy 4-AcO-MET Online France

What is 4-AcO-MET?

4-AcO-MET (4-Acetoxy-N-methyl-N-ethyltryptamine) is a synthetic molecule of the tryptamine class and the acetate ester of 4-HO-MET (Metocin). It is a structural homologue of psilacetin (4-AcO-DMT). At Chemssupply.eu, we provide high-purity 4-AcO-MET as a stable crystalline salt (typically fumarate or HCl). As a leading EU chemical supplier, we ensure our 4-AcO-MET meets the analytical requirements for advanced neurochemical and forensic laboratories. Buy 4-AcO-MET Online In Europe

How It Works

In laboratory settings, 4-AcO-MET is primarily researched as a prodrug of 4-HO-MET. Scientific literature, such as data hosted on NCBI PubMed, indicates that it is quickly hydrolyzed into its phenolic counterpart by serum esterases.

Researchers focus on its role as a 5−HT receptor agonist, studying how the asymmetric N-methyl-N-ethyl substitution affects binding kinetics and metabolic clearance compared to symmetric N,N-dialkyl tryptamines. Its stable molecular framework is essential for GC/MS calibration, receptor binding assays, and Structure-Activity Relationship (SAR) mapping.

Benefits and Features

Asymmetric N-Alkyl Chain: A vital subject for investigating the impact of combined methyl and ethyl groups on tryptamine pharmacodynamics.

HPLC Verified Purity: We guarantee 98%+ verified purity, ensuring a clean analytical baseline free from synthesis-related impurities.

Enhanced Shelf-Life: The acetoxy group provides superior stability against oxidation compared to 4-hydroxy tryptamines, making it ideal for long-term study.

Distinct Analytical Profile: 4-AcO-MET exhibits a specific fragmentation pattern for high-resolution mass spectrometry, as referenced in European Union Early Warning System (EWS) reports.

REACH & ECHA Compliant: Fully documented according to the latest European Chemicals Agency (ECHA) safety and distribution standards (2026).

Safety and Handling

When you order 4-AcO-MET online in Europe, maintaining strict laboratory safety protocols is mandatory.

In-Vitro Laboratory Use Only: 4-AcO-MET is intended strictly for forensic, analytical, and academic research. It is not for human or animal consumption.

PPE Protocols: Researchers must wear nitrile gloves, laboratory coats, and eye protection. All chemical manipulation should occur in a certified fume hood.
