Product Specifications

Applications & Usage

MPT Fumarate (N-Methyl-N-propyltryptamine) is intended for forensic, analytical, and pharmacological research only. Typical applications include:

1. Serotonin Receptor Binding Assays – Investigate affinity (Ki) and functional activity (EC50) at 5-HT1A, 5-HT2A, 5-HT2B, and 5-HT2C receptors. Compare MPT binding profiles with DMT (N,N-dimethyl), NMT (N-methyl), DPT (N,N-dipropyl), and MET (N-methyl-N-ethyl) to map the alkyl chain length-activity relationship.
2. Structure-Activity Relationship (SAR) Studies – Use MPT as a model compound to understand how asymmetric amine substitution affects receptor selectivity. The propyl group introduces additional hydrophobic interactions that are not possible with ethyl or methyl groups alone.
3. Metabolic Stability Investigations – Evaluate hepatic microsomal degradation pathways using pooled human liver microsomes (HLM). Identify major phase I metabolites (N-dealkylation, oxidation) via LC-MS/MS. Compare the metabolic half-life of the N-methyl vs. N-propyl groups.
4. Analytical Reference Standard – Use as a calibrant for HPLC-UV, GC-MS, or LC-MS/MS in forensic toxicology laboratories for seized drug analysis and biological matrix screening.
5. In Vitro Toxicology Screening – Assess cytotoxicity (MTT assay), hERG channel liability (patch-clamp), or genotoxicity (Ames test) in validated cell-based models.
6. Lipophilicity and Membrane Permeability Studies – Determine logP values using shake-flask or HPLC methods. Evaluate passive membrane permeability using PAMPA or Caco-2 cell monolayers. Compare the effect of the propyl group on blood-brain barrier penetration.

Researchers must follow institutional animal care and use committee (IACUC) or institutional review board (IRB) protocols where applicable and comply with all local regulations regarding tryptamine derivatives.

Purity & Testing

Reproducible science demands verifiable purity. At RChems EU, every batch of MPT Fumarate for research undergoes a comprehensive analytical workflow before release:

• High-Performance Liquid Chromatography with Diode Array Detection (HPLC-DAD) – Quantifies purity at ≥99% using dual wavelengths (254 nm and 280 nm). Any impurity peak >0.1% area triggers batch rejection. Full chromatograms are included in the CoA.
• Nuclear Magnetic Resonance (NMR) Spectroscopy – ¹H NMR (400 MHz, DMSO-d₆ or CDCl₃) confirms the presence of the indole NH (δ 10.85 ppm, broad singlet), the N-methyl singlet (δ 2.35 ppm, 3H), the N-propyl triplet (δ 0.92 ppm, 3H) and multiplet (δ 1.55 ppm, 2H), and the side chain methylene groups. The fumarate counterion appears as a characteristic singlet at δ 6.62 ppm (2H). ¹³C NMR verifies the fumarate carbonyl signals at approximately 167 ppm.
• High-Resolution Mass Spectrometry (HRMS-ESI-TOF) – Confirms exact mass [M+H]⁺ calculated for C₁₄H₂₁N₂⁺: 217.1699; found: 217.1695 ± 2 ppm. Mass accuracy within 3 ppm confirms molecular identity.
• Fumarate Counterion Confirmation – Ion chromatography (IC) or quantitative NMR (qNMR) confirms 1:1 fumarate:MPT stoichiometry.
• Loss on Drying (LOD) – Maintained below 0.5% to prevent hydrolytic degradation during long-term storage.
• Residual Solvent Analysis (GC-FID) – Validates that all manufacturing solvents (ethyl acetate, hexane, methanol, diethyl ether) are below ICH limits.
• Heavy Metals (ICP-MS) – Confirms lead, arsenic, cadmium, and mercury are below 20 ppm.

When you purchase 99% pure MPT Fumarate, you eliminate variability caused by unreacted precursors (e.g., tryptamine, methylating agents, propyl halides), deaminated byproducts, or residual solvents. This level of purity is essential for publication-ready data and cross-laboratory reproducibility in SAR studies.

Each shipment includes a batch-specific Certificate of Analysis (CoA) with full chromatograms, spectral summaries, and a list of all tested impurities. For GMP or GLP compliance, third-party testing through an accredited ISO/IEC 17025 laboratory can be arranged at an additional cost.

FAQ Section

1. What is MPT Fumarate (N-Methyl-N-propyltryptamine) used for in research?

MPT Fumarate is used as a research tool to study serotonin receptor pharmacology, specifically 5-HT2A and 5-HT1A receptor binding and functional activity. The mixed N-methyl and N-propyl substitution pattern allows researchers to investigate how asymmetric alkyl chain length affects receptor affinity, selectivity, and intrinsic activity. It is particularly valuable for SAR studies comparing symmetric (DMT, DPT) and asymmetric (MET, MPT, EPT) tryptamines. It is also used as an analytical reference standard in forensic toxicology and as a substrate for metabolic stability assays.

2. Is MPT Fumarate legal?

Legal status varies significantly by country and jurisdiction. In the United States, the Federal Analogue Act may apply if the compound is structurally similar to a Schedule I substance (e.g., DMT) and intended for human consumption. RChems EU sells this product strictly for legitimate research purposes (e.g., in vitro receptor assays, HPLC calibration, forensic analysis). You are solely responsible for verifying local laws before ordering. We do not ship to countries with blanket bans on tryptamine derivatives (Japan, Sweden, Norway, China) without a valid research license and import permit. Contact our compliance team if you are unsure about your jurisdiction.

3. How discreet is shipping from RChems EU?

Maximum discretion. Your order arrives in a plain, unmarked corrugated cardboard box or padded envelope with no logos, no brand identifiers, and no chemical names. The return address is a generic logistics center (not “RChems EU” or any chemical reference). The customs declaration reads “Non-hazardous laboratory reagent,” “Stability test samples,” or “Organic salt for research.” Inside, the product is vacuum-sealed in an opaque Mylar bag with a desiccant pouch and oxygen absorber. No chemical names (including “N-Methyl-N-propyltryptamine” or “MPT”), CAS numbers, hazard diamonds, or company branding appear anywhere on the outer parcel. Your privacy is fully protected. We have maintained a 99.5% successful delivery rate over 9 years of operation.

4. What is the purity level of MPT Fumarate, and how is it tested?

Every batch is ≥99% pure as measured by HPLC-DAD (dual wavelength, area normalization). The full testing panel includes:

• HPLC-DAD (254 nm and 280 nm; full chromatogram provided)
• ¹H NMR and ¹³C NMR (structural confirmation; spectra provided, including fumarate counterion confirmation)
• High-resolution mass spectrometry (HRMS-ESI-TOF) (mass accuracy <3 ppm)
• Ion chromatography or qNMR (fumarate counterion ratio confirmation)
• Residual solvent analysis (GC-FID; meets ICH Q3C limits)
• Loss on drying (typically <0.5%)
• Heavy metals (ICP-MS; <20 ppm)

A Certificate of Analysis (CoA) with all raw data (chromatograms, spectra, and summary tables) is included with every order. Third-party testing via an accredited ISO/IEC 17025 laboratory is available for an additional fee.

5. Why is MPT supplied as a fumarate salt rather than a freebase or hydrochloride?

The fumarate salt offers several advantages for research applications compared to the freebase or hydrochloride (HCl) salt:

• Enhanced stability – Fumarate salts are typically less hygroscopic than HCl salts, reducing moisture absorption during storage.
• Improved aqueous solubility – Fumarate salts often exhibit better solubility in water and biological buffers, which is essential for in vitro receptor binding assays and cell-based studies.
• Gentle counterion – Fumaric acid is a naturally occurring organic acid (intermediate in the citric acid cycle) and is less likely to cause protein precipitation or pH extremes in assay buffers compared to HCl.
• Crystalline properties – The fumarate salt tends to form well-defined crystals, facilitating accurate weighing and handling.

If your research requires the freebase or another salt form, please contact our scientific support team for custom synthesis options.

6. How should I store MPT Fumarate?

Store in a refrigerator (2–8°C / 36–46°F) inside a tightly sealed, amber glass vial with a PTFE-lined cap. Add a silica gel desiccant packet to absorb moisture. Keep away from direct light and humidity. Under these conditions, the compound is stable for at least 24 months. Do not store at room temperature for extended periods, as the fumarate salt may absorb atmospheric moisture, leading to caking or degradation. Avoid repeated freeze-thaw cycles. Do not store near strong oxidizing agents or strong acids.

8. How does MPT differ from other tryptamines like DMT, MET, or DPT for research purposes?

MPT occupies a unique position in tryptamine SAR space:

• vs. DMT (N,N-dimethyl) – MPT replaces one methyl group with a propyl group, increasing lipophilicity and potentially altering receptor binding kinetics. This allows researchers to study the effect of extending one alkyl chain while keeping the other short.
• vs. MET (N-methyl-N-ethyl) – MPT has a propyl group instead of an ethyl group, adding two additional methylene units. This enables investigation of the optimal alkyl chain length for hydrophobic pocket interactions within the 5-HT2A binding site.
• vs. DPT (N,N-dipropyl) – MPT has one methyl and one propyl, making it asymmetric. Comparing MPT with DPT helps researchers understand whether symmetric vs. asymmetric substitution affects receptor selectivity and functional activity.
• vs. NMT (N-methyl) – MPT adds a second alkyl group (propyl), converting a secondary amine to a tertiary amine, which significantly affects basicity, hydrogen bonding capacity, and overall molecular shape.

These subtle structural differences make MPT an essential reference compound for comprehensive tryptamine SAR studies.

9. What happens if my package is seized by customs?

While less than 1% of our shipments experience customs issues (excluding prohibited destinations), if your package is seized due to regulatory enforcement in your country (and you are not in a banned country and have not violated local import laws), RChems EU will offer either:

• One free reshipment to an alternate address within the same country, or
