5-MAPB (Benzofuran) – N-Methyl-5-(2-aminopropyl)benzofuran Reference Standard

In the benzofuran family of research compounds, isomer specificity is the single most critical quality metric. 5-MAPB (benzofuran) (1-(benzofuran-5-yl)-N-methylpropan-2-amine) is the N-methyl analog of 5-APB, and it is frequently confused with its 6-position isomer (6-MAPB) in unverified market streams. ChemNexis Pharma supplies 5-MAPB (benzofuran) as a verified benzofuran reference standard, distinguishing the 5-substituted scaffold from the 6-substituted variant through rigorous NMR and LC-MS validation. Whether you are sourcing for analytical method development or collection curation, our 5-MAPB (benzofuran) inventory guarantees the correct regiochemistry.

We operate as a direct-to-buyer supplier, eliminating the reseller markup and documentation gaps common in this niche. Every order of 5-MAPB ships with a lot-matched Certificate of Analysis (COA) and is dispatched in discreet, unbranded packaging within 24 hours. Secure your allocation of this high-demand benzofuran today.

 

The Benzofuran Scaffold: 5-Position vs. 6-Position

The primary analytical challenge with 5-MAPB (benzofuran) is differentiating it from 6-MAPB. While both share the same molecular formula and mass, their retention times and fragmentation patterns differ significantly on chromatographic systems. The 5-position isomer (benzofuran-5-yl) exhibits distinct lipophilicity compared to the 6-position isomer, a critical variable for HPLC method validation. You can verify the exact structural topology of the 5-substituted benzofuran core via the PubChem compound registry. Our 5-MAPB (benzofuran) stock is synthesized to ensure >99% isomeric purity, eliminating the “double peak” interference that plagues lower-grade benzofuran suppliers.

Where to Buy 5-MAPB: Supplier Verification & Pricing

Finding a reliable 5-MAPB supplier requires looking beyond the sticker price to the documentation chain. Many vendors list “5-MAPB” but ship 6-MAPB or uncharacterized mixtures. We provide a transparent price per gram structure with volume discounts for bulk and wholesale orders. Our 5-MAPB is available for immediate sale in secure, moisture-proof amber glass. For laboratories and collectors asking “where to buy 5-MAPB (benzofuran) in bulk,” we offer custom synthesis quotes and kilogram-scale pricing upon request. Check our live inventory to see why we are rated the best 5-MAPB (benzofuran) company for analytical integrity.

Analytical Workflow: LC-MS/MS & GC-MS Profiling

For forensic and toxicological applications, 5-MAPB (benzofuran) is typically analyzed via LC-MS/MS in positive electrospray ionization (ESI+) mode. The protonated molecule [M+H]+ appears at m/z 190.1, with characteristic product ions resulting from the benzofuran ring cleavage and amine side-chain loss. Unlike the methylenedioxyphenyl (MDA/MDMA) class, the benzofuran ring system offers superior stability against oxidative degradation, making 5-MAPB an excellent candidate for long-term reference libraries. Cross-reference our spectral data with the UNODC NPS monitoring lists to ensure your library is current with international scheduling updates.

Storage, Stability, and Handling

5-MAPB (benzofuran) is a stable solid when protected from light and moisture. We recommend storing the amber vials at room temperature (20-25°C) in a desiccated environment. Under these conditions, the benzofuran scaffold retains its chemical integrity for over 24 months. Avoid prolonged exposure to UV light, which can induce photodegradation of the furan ring. Always handle with standard PPE (gloves, eye protection) as per the Safety Data Sheet (SDS) provided with every order.

Global Shipping & Discreet Packaging

We understand that privacy is paramount for our buyers. All 5-MAPB (benzofuran) orders are packed in plain, unbranded boxes with no external indication of the contents. We ship daily to the USA, Europe, Australia, and beyond, using tracked express services that ensure your research materials arrive safely and discreetly. Our logistics team monitors customs regulations in real-time to minimize delivery friction.

Frequently Asked Questions

What is the difference between 5-MAPB (benzofuran) and 6-MAPB?
They are regioisomers. 5-MAPB has the aminopropyl chain at the 5-position of the benzofuran ring, while 6-MAPB has it at the 6-position. They have different retention times in HPLC and distinct fragmentation patterns in mass spectrometry.

Is this 5-MAPB (benzofuran) sold as a freebase or salt?
Our specification sheet lists the freebase molecular weight (189.25 g/mol) for analytical consistency, but the product is stabilized for optimal shelf-life. The COA will specify the exact salt form (e.g., succinate or fumarate) if applicable to the specific batch.

Do you offer bulk pricing for 5-MAPB?
Yes, we offer tiered pricing for wholesale and bulk orders. Contact our sales team for a custom quote on quantities above 100g.
