O-DSMT

Buy O-DSMT Research Chemical Online – USA, Europe & Worldwide

In the field of opioid receptor pharmacology, the study of active metabolites provides critical insights into drug metabolism, receptor selectivity, and therapeutic index. O-DSMT (O-Desmethyltramadol) represents a compound of significant interest: it is the major phase I metabolite of tramadol, produced via O-demethylation by the cytochrome P450 enzyme CYP2D6. Unlike tramadol itself—which is a prodrug with weak µ-opioid affinity—O-DSMT demonstrates substantially higher potency at the µ-opioid receptor while retaining norepinephrine and serotonin reuptake inhibition properties.

When you buy O-DSMT from RChems EU, you acquire a high-purity research compound manufactured under strict quality controls. Our 99% pure O-DSMT is intended exclusively for laboratory research—not for human or animal consumption. Whether you are conducting radioligand binding assays, evaluating G-protein activation pathways, or exploring metabolic stability in hepatic microsomes, this compound provides the consistency your work demands.

Applications & Usage

⚠️ Strictly for laboratory research use only. Not for human or animal consumption.

O-DSMT is utilized in a range of non-clinical, pre-clinical, and basic science research applications. Typical areas of investigation include:

• Opioid Receptor Binding Studies: Evaluating affinity (Ki) and selectivity for µ-opioid receptor (MOR), δ-opioid receptor (DOR), and κ-opioid receptor (KOR) using radioligand displacement assays (e.g., [³H]-DAMGO for MOR).
• G-protein Activation Assays: Measuring [³⁵S]GTPγS binding to assess efficacy and potency at MOR in CHO cell membranes or brain homogenates.
• Monoamine Transporter Inhibition: Investigating norepinephrine (NET) and serotonin (SERT) reuptake inhibition using synaptosomal uptake inhibition assays.
• Metabolic Stability Research: Evaluating hepatic microsomal or S9 fraction metabolism (phase I and phase II) using LC-MS/MS quantification.
• Analytical Reference Standard: Serving as a high-purity calibrant for forensic toxicology or pharmaceutical impurity profiling.
• Structure-Activity Relationship (SAR) Studies: Comparing O-DSMT with tramadol and other 2-[(dimethylamino)methyl]-1-hydroxycyclohexylphenol derivatives.

Researchers are encouraged to consult peer-reviewed literature (e.g., Journal of Pharmacology and Experimental Therapeutics, European Journal of Pharmacology) for established in vitro protocols. RChems EU does not provide research protocols but guarantees the compound’s structural integrity and purity for such applications.

Purity & Testing

Reproducibility in opioid receptor pharmacology depends critically on compound purity. Impurities—particularly other opioid receptor ligands or oxidative degradation products—can produce false-positive signals in GTPγS binding assays or confound radioligand displacement curves. That is why 99% pure O-DSMT from RChems EU is subjected to a multi-laboratory quality control workflow:

1. High-Performance Liquid Chromatography (HPLC-DAD): Quantitative analysis at 215 nm and 270 nm. Minimum acceptance criterion: ≥99.0% peak area purity.
2. Liquid Chromatography-Mass Spectrometry (LC-MS): Confirms molecular ion [M+H]⁺ = 250.2 (freebase) and detects trace-level organic impurities down to 0.05%.
3. Nuclear Magnetic Resonance (NMR): Both proton (¹H) and carbon-13 (¹³C) NMR verify the correct cyclohexyl ring substitution, phenolic OH group, and dimethylaminomethyl side chain. Any spectral deviation triggers batch rejection.
4. Residual Solvent Analysis (GC-MS): Ensures compliance with ICH limits for Class 2 and Class 3 solvents.
5. Heavy Metal Testing (ICP-MS): Confirms levels below 20 ppm for lead, arsenic, cadmium, and mercury.
6. Isomeric Purity: Confirmed by chiral HPLC to ensure >98% trans isomer (the pharmacologically active form).

Each batch is assigned a unique lot number, and a Certificate of Analysis (COA) is available upon request. This rigorous testing ensures that when you buy O-DSMT for research, you receive a compound that performs consistently from order to order.

FAQ Section

1. What is O-DSMT used for in research?

O-DSMT (O-Desmethyltramadol) is used in neuropharmacological research to study µ-opioid receptor agonism, norepinephrine and serotonin reuptake inhibition, and the pharmacology of active drug metabolites. Typical applications include radioligand binding assays, [³⁵S]GTPγS functional assays, synaptosomal uptake inhibition studies, and hepatic microsomal metabolism experiments.

2. Is O-DSMT legal to buy and possess for research?

Legality depends on your jurisdiction. In the United States, O-DSMT is not explicitly scheduled federally but may be considered a controlled substance analogue under the Federal Analogue Act (21 U.S.C. § 813) if intended for human consumption. Many European countries (e.g., Germany, Sweden, Finland) have scheduled O-DSMT as a controlled substance. You must check your local regulations before ordering. RChems EU ships on the condition that you assume full legal responsibility.

3. How discreet is the shipping from RChems EU?

Extremely discreet. All O-DSMT orders are shipped in plain, unmarked packaging with no external branding. The shipping label uses a generic return address. Inner bags are vacuum-sealed with no chemical names or CAS numbers visible. Our stealth protocol has enabled successful deliveries to over 45 countries with a 99%+ success rate.

4. What is the guaranteed purity level of your O-DSMT?

Every batch of O-DSMT from RChems EU is independently tested to be ≥99% pure via HPLC-DAD, with confirmation by LC-MS and ¹H/¹³C NMR. Chiral HPLC confirms isomeric purity (>98% trans isomer). A lot-specific Certificate of Analysis (COA) is available for every order upon request.

5. How is the 99% purity tested?

We employ a five-tier analytical protocol:

• HPLC-DAD for quantitative purity (≥99% peak area at 215 nm and 270 nm).
• LC-MS for molecular weight confirmation ([M+H]⁺ = 250.2 for freebase) and trace impurity detection.
• ¹H and ¹³C NMR for structural confirmation (cyclohexyl ring, phenolic OH, dimethylaminomethyl side chain).
• GC-MS for residual solvent analysis (ICH compliance).
• Chiral HPLC to confirm trans isomer purity (>98%).

All testing is performed by an ISO 17025-accredited contract laboratory.

6. Can you ship O-DSMT to my country (USA, UK, Germany, Australia, Canada)?

RChems EU ships O-DSMT worldwide, including the USA, Canada, United Kingdom, Germany, France, Italy, Spain, Netherlands, Switzerland, Norway, Australia, and New Zealand. However, due to varying legal statuses, we strongly recommend contacting our support team before ordering if you are located in Germany, Sweden, Finland, or any country with specific opioid analog legislation. For countries with strict import controls (e.g., Japan, Singapore, South Korea), we do not currently ship O-DSMT.

7. How should I store O-DSMT after delivery?

Store O-DSMT in a tightly sealed, amber glass vial away from light, heat, and moisture. For short-term use (≤3 months), room temperature (20–25°C) in a desiccator is acceptable. For long-term storage (>3 months), refrigerate at 4°C. Always allow the sealed container to reach room temperature before opening to prevent condensation-induced degradation.

8. What is the difference between O-DSMT and tramadol?

Tramadol is a prodrug that requires CYP2D6-mediated O-demethylation to produce O-DSMT, the primary active metabolite. O-DSMT has approximately 6-fold higher affinity for the µ-opioid receptor compared to tramadol and is responsible for the majority of tramadol’s opioid activity in research models. Unlike tramadol, O-DSMT is not a prodrug and does not require metabolic activation, making it a more direct tool for opioid receptor studies.

9. Do you offer a reshipment policy if customs seizes my package?

Yes. RChems EU offers a one-time reshipment policy for confirmed customs seizures in most countries, provided that the original shipping address is valid and the buyer did not violate known local laws. Crypto payments qualify for the full reshipment guarantee. Terms and conditions apply—please contact customer support for details.

10. Can I get a Certificate of Analysis (COA) before ordering?

Absolutely. Contact our support team via email with the product name (O-DSMT) and your research affiliation. We will provide a redacted or full COA for the current batch, including HPLC chromatograms, NMR spectra, and chiral purity data, subject to verification of legitimate research intent.
