Buy Escaline Fumarate Research Chemical Online – USA, Europe & Worldwide
Escaline fumarate (CAS No. 39201-82-6 as freebase; fumarate salt custom synthesized) is a 4-ethoxy-3,5-dimethoxyphenethylamine derivative representing a key molecular tool for serotonergic receptor pharmacology. Compared to the hydrochloride salt, the fumarate form offers enhanced crystallinity, reduced hygroscopicity, and improved long-term stability – critical attributes for reproducible in vitro assays and long-term storage studies. Researchers seeking to explore structure-activity relationships (SAR) among mescaline analogs frequently turn to Escaline as a reference compound due to its well-documented affinity for 5-HT₂A and 5-HT₂C receptors. RChems EU supplies Escaline fumarate at 99%+ purity, with each batch validated by orthogonal analytical methods. Whether you need to buy Escaline fumarate for radioligand binding assays, receptor functional studies, or as an analytical standard, our global logistics infrastructure ensures fast, discreet delivery to accredited laboratories across the USA, Europe, Australia, and Asia.

Important: This product is NOT for human or veterinary consumption, food additives, cosmetics, or any form of in vivo human or animal testing not approved by an institutional animal care and use committee (IACUC).
Purity & Testing – Why 99% Matters for Reproducible Research
Research reproducibility depends on compound integrity. Impurities at levels as low as 1–2% can:
- Compete with the parent compound at receptor sites, confounding affinity measurements.
- Produce off-target effects misinterpreted as the test article’s pharmacology.
- Accelerate degradation, leading to concentration drift in long-term studies.
RChems EU implements a rigorous three-tier analytical protocol for every batch of Escaline fumarate:
| Method | Purpose |
|---|---|
| HPLC-DAD (210 nm & 254 nm) | Quantifies main component purity and detects organic impurities down to 0.05% area. |
| GC-MS (EI, 70 eV) | Confirms identity via retention index and fragmentation pattern; detects volatile impurities. |
| ¹H & ¹³C NMR (400 MHz, DMSO-d₆) | Verifies structural integrity, salt stoichiometry (1:1 fumarate), and absence of positional isomers. |
Additionally, each batch is screened for:
- Residual solvents (by headspace GC) per ICH Q3C guidelines.
- Heavy metals (by ICP-MS).
- Water content (Karl Fischer coulometric titration).
Only lots meeting ≥99% purity across all orthogonal methods are released. Your order includes a signed CoA with raw chromatograms and NMR spectra. This transparency ensures that when you buy Escaline fumarate 99% pure from RChems EU, you are buying confidence in your data.

FAQ Section
1. What is Escaline fumarate used for in research?
Escaline fumarate is used as a pharmacological tool to study serotonin 5-HT₂A and 5-HT₂C receptor function. Common applications include in vitro radioligand binding assays, in vivo rodent behavioral models (head-twitch response), structure-activity relationship studies of mescaline analogues, and as an analytical reference standard for forensic toxicology.
2. Why choose the fumarate salt over the hydrochloride salt for research?
The fumarate salt of Escaline offers lower hygroscopicity (less water absorption from air), improved crystallinity, and enhanced long-term stability during room-temperature storage or weighing. For researchers performing precise gravimetric measurements without a humidity-controlled glovebox, Escaline fumarate is often preferred.
3. Is Escaline fumarate legal to buy and import?
Legality varies significantly by jurisdiction. In the United States, Escaline is not federally scheduled but could be considered an analogue of mescaline under the Federal Analogue Act if intended for human consumption. For legitimate in vitro research, most US laboratories operate compliantly. In the UK, Escaline is a Class A drug under the Misuse of Drugs Act as a phenethylamine derivative. In Canada, it may fall under Schedule III. Always check your local laws before purchasing.
4. How discreet is shipping from RChems EU?
Extremely discreet. Our standard protocol uses plain cardboard boxes or bubble mailers with no logos or company name. The customs declaration states “Laboratory reagent” or “Chemical sample for research.” The inner vacuum-sealed bag has a small batch label but does not include the product name (only “Research Sample” and a batch code). No one handling the parcel will know it contains Escaline fumarate.
5. What is the guaranteed purity, and how is it tested?
Minimum purity is 99% as measured by HPLC-DAD at two wavelengths (210 nm and 254 nm). Every batch is also tested by GC-MS for volatile impurities, ¹H NMR and ¹³C NMR for structural verification and salt stoichiometry, Karl Fischer for water content, and ICP-MS for heavy metals. A signed Certificate of Analysis with raw data is included with every order.
6. How should I store Escaline fumarate for maximum shelf life?
Store at -20°C in the original vacuum-sealed bag with desiccant, inside an amber glass vial with PTFE-lined cap. Under these conditions, stability exceeds 24 months. For frequent use, prepare aliquots and store at -20°C; avoid repeated freeze-thaw cycles. At +4°C (refrigerated), use within 3–6 months. Do not store above 25°C.
7. Can I receive a Certificate of Analysis before placing an order?
Yes. Contact our customer support team via the website with your request and the batch reference shown on the product page (or request a previous batch’s CoA). We will email you a PDF containing the HPLC chromatogram, NMR spectra, and purity summary – all before you decide to purchase.
8. What happens if my package is seized by customs?
Seizure is rare due to our discreet packaging, but if it occurs and you provide official customs seizure documentation, RChems EU offers one reshipment at 50% cost or a 70% store credit. Refunds are not provided for shipping costs. We do not reship to countries with known high seizure rates without prior agreement.
