Buy 5-MAPB Powder Online – (5‑(2‑Methylaminopropyl)benzofuran) — Analytical & Regulatory
Buy 5-MAPB powder is a synthetic benzofuran analogue of amphetamine, belonging to the entactogen / empathogen subgroup of substituted phenethylamines.
Structurally related to MDMA and 5‑APB, it has been identified in unregulated “research chemical” markets prior to its control.
Now legally restricted, it is of interest to analytical chemists and forensic laboratories for reference and identification.
Organic / Inorganic Chemistry
| Property | Description |
|---|---|
| IUPAC name | 1‑(benzofuran‑5‑yl)‑N‑methylpropan‑2‑amine |
| Empirical formula | C₁₂H₁₇NO |
| Molecular mass | 191.27 g · mol⁻¹ |
| Functional groups | Secondary amine (N‑methyl‑isopropyl), benzofuran ring. |
| Appearance | Off‑white / beige crystalline powder (usually HCl salt). |
| Boiling point (freebase) | ~ 270 °C (decomp.). |

Chemical Biology
- Neurochemical Profile: Acts as a serotonin‑releasing agent with secondary dopamine and noradrenaline activity.
- Binding Sites: SERT > DAT > NET (in vitro assays).
- Mechanism: Monoamine transporter substrate; increases extracellular 5‑HT.
- Metabolism: Demethylation and β‑hydroxylation → catecholic metabolites; MAO‑dependent deamination.
- Biological use: Research on structure–activity relationships (SAR) and receptor modeling.
- Toxicology: Limited data; potential for hyperthermia, hypertension, and neurotransmitter depletion.
