Buy 3‑MEC powder is a β‑keto analog of 3‑methylmethcathinone (3‑MMC) and a derivative of cathinone, differing by N‑ethyl substitution.
It is primarily studied as part of forensic drug profiling, toxicology, and SAR (structure–activity relationship) work comparing substituted cathinones.
Organic / Inorganic Chemistry
| Property | Information |
|---|---|
| IUPAC Name | 2‑ethylamino‑1‑(3‑methylphenyl)‑1‑propanone |
| Molecular Formula | C₁₂H₁₇NO |
| Molecular Weight | 191.27 g · mol⁻¹ |
| Chemical Class | β‑keto phenethylamine (cathinone derivative) |
| Functional Groups | Ketone, secondary amine, aromatic ring |
| Physical Form | Off‑white to beige crystalline powder (HCl salt) |
| Melting Point | ≈ 171–174 °C (HCl form) |

Chemical Biology
- Mechanistic Class: Monoamine transporter substrate / releaser (stimulant profile).
- Primary Targets: Dopamine (DAT), norepinephrine (NET), and serotonin (SERT) transporters.
- Research Use: Forensic standard for LC–MS screening of synthetic cathinones.
- Metabolism (in vitro): N‑deethylation → 3‑methylcathinone, reduction of β‑ketone → alcohol metabolite, followed by conjugation.
- Comparative SAR: N‑ethyl substitution increases lipophilicity, reduces SERT/DAT selectivity, and modifies duration of action in receptor assays.
