5-EAPB (Benzofuran) – N-Ethyl-5-(2-aminopropyl)benzofuran Reference Standard

In the benzofuran family of research compounds, N-alkyl chain elongation is the primary variable that shifts receptor affinity and lipophilicity. 5-EAPB (1-(benzofuran-5-yl)-N-ethylpropan-2-amine) is the N-ethyl analog of 5-APB, sitting structurally between the primary amine (5-APB) and the N-methyl analog (5-MAPB). ChemNexis Pharma supplies 5-EAPB (Benzofuran) as a verified reference standard, distinguishing the N-ethyl substitution through rigorous NMR and LC-MS validation. Whether you are sourcing for analytical method development or collection curation, our inventory guarantees the correct chain elongation.

As the best 5-EAPB supplier for analytical integrity, we operate as a direct-to-buyer distributor, eliminating the reseller markup and documentation gaps common in this niche. Every order 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 at the most affordable 5-EAPB (Benzofuran) rates on the market.

 

The N-Alkyl Chain: 5-EAPB vs 5-MAPB vs 5-APB

The primary analytical challenge with 5-EAPB (Benzofuran) is differentiating it from its N-methyl and primary amine counterparts. While all three share the same benzofuran-5-yl core, their exact masses and fragmentation patterns differ significantly on chromatographic systems. The N-ethyl group adds 14 Da (a CH2 unit) compared to 5-MAPB, and 28 Da compared to 5-APB. You can verify the exact structural topology of the N-ethyl substituted benzofuran core via the PubChem compound registry. Our high-quality 5-EAPB (Benzofuran) stock is synthesized to ensure >99% isomeric purity, eliminating the cross-contamination that plagues lower-grade benzofuran vendors.

Where to Buy 5-EAPB: Wholesale Pricing & Verification

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

Analytical Workflow: LC-MS/MS Profiling

For forensic and toxicological applications, 5-EAPB is typically analyzed via LC-MS/MS in positive electrospray ionization (ESI+) mode. The protonated molecule [M+H]+ appears at m/z 208.1, with characteristic product ions resulting from the benzofuran ring cleavage and the ethylamine side-chain loss. Unlike the methylenedioxyphenyl (MDA/MDMA) class, the benzofuran ring system offers superior stability against oxidative degradation, making 5-EAPB 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-EAPB 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.

Frequently Asked Questions

What is the difference between 5-EAPB and 5-MAPB?
They differ by the N-alkyl chain. 5-EAPB has an N-ethyl group, while 5-MAPB has an N-methyl group. This 14 Da mass difference is easily resolved on high-resolution mass spectrometry.

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

Is this 5-EAPB sold as a freebase or salt?
Our specification sheet lists the freebase molecular weight (207.28 g/mol) for analytical consistency, but the product is stabilized for optimal shelf-life. The COA will specify the exact salt form if applicable to the specific batch.
