Introduction to Buy MDPHP Powder (Freebase)
Buy MDPHP Powder (Freebase) (3′,4′-Methylenedioxy-α-pyrrolidinohexanophenone), commonly referred to as MDPHP, is a highly potent, synthetic substituted cathinone belonging to the pyrrolidinophenone class. Structurally, it is the extended α-carbon chain (hexanophenone) analog of the well-documented MDPV (Methylenedioxypyrovalerone). In neuropharmacological research, MDPHP is classified as a potent dopamine-norepinephrine reuptake inhibitor (DNRI), making it a critical reference standard for studying catecholamine transporter dynamics and stimulant pharmacokinetics.
Supplied in the freebase form, MDPHP offers unique advantages for lipophilicity assays and non-polar solvent preparation, but it also requires specialized handling. Unlike stable hydrochloride (HCl) salts, the freebase form of synthetic cathinones is inherently less stable, highly lipophilic, and prone to degradation or physical state changes at room temperature. Because of this, it is strictly reserved for advanced laboratory environments equipped for its specific storage and handling requirements. Note: This product is strictly intended for in-vitro research and analytical purposes only.
Key Features and Benefits – Buy MDPHP Powder (Freebase)
- Freebase Lipophilicity Modeling: The non-ionized freebase form is highly lipophilic, making it the preferred reference standard for passive diffusion assays, blood-brain barrier (BBB) penetration modeling, and non-polar solvent volumetrics.
- DNRI Mechanism Research: MDPHP provides researchers with a potent tool to study the structural-activity relationships (SAR) of compounds that selectively block dopamine (DAT) and norepinephrine (NET) transporters without releasing endogenous neurotransmitters.
- α-Carbon Chain SAR Studies: Essential for mapping how the extension of the α-carbon chain (pentanophenone vs. hexanophenone) alters DAT/NET affinity and metabolic stability compared to MDPV.
- Raw Powder Versatility: Allows for the creation of precise, custom-concentration solutions tailored to unique analytical assay requirements, free from the hydrochloride salt matrix.

Disclaimer: This product is not for human or veterinary consumption. It must only be handled in controlled laboratory environments by qualified professionals.
Purity and Testing
We guarantee a purity level of ≥ 98% for our MDPHP (Freebase). Every batch undergoes rigorous, independent third-party testing to verify chemical identity, absolute purity, and the absence of dangerous residual solvents, heavy metals, or unreacted precursors (such as piperonal or pyrrolidine). Because freebase cathinones are prone to oxidation, special analytical care is taken to ensure minimal presence of degradation products. Certificates of Analysis (CoA) and Safety Data Sheets (SDS) are provided upon request.
Safety and Handling
WARNING: MDPHP IS A HIGHLY POTENT STIMULANT RESEARCH CHEMICAL IN A VOLATILE FREEBASE FORM. EXTREME CAUTION IS REQUIRED.

Frequently Asked Questions (FAQ)
Q1: What is the difference between MDPHP Freebase and MDPHP HCl?
A: The freebase form is the un-ionized base molecule, making it highly lipophilic, non-polar, and better suited for BBB permeability assays. However, it is physically unstable, often appearing as a waxy resin or oil. The HCl salt form is an ionized, crystalline powder that is water-soluble and highly stable, making it easier to weigh for standard aqueous biological assays.
Q2: My MDPHP Freebase arrived as an oily/waxy lump instead of a dry powder. Is it defective?
A: No. This is a normal physical property of freebase synthetic cathinones. At room temperature or slightly above, the freebase form of MDPHP frequently melts into a viscous oil or waxy resin. It is chemically intact. To handle it, place the sealed vial in a freezer (-20°C) for 30–60 minutes. It will solidify, allowing you to safely weigh or transfer it.
Q3: What makes MDPHP different from MDPV?
A: Both are pyrrolidinophenone cathinones and potent DNRIs. MDPHP features a hexanophenone structure (a 6-carbon chain), whereas MDPV features a pentanophenone structure (a 5-carbon chain). This structural difference alters its metabolic stability and receptor kinetics, making it highly valuable for comparative SAR (Structural-Activity Relationship) research.
Q4: Can MDPHP Freebase be consumed?
A: Absolutely not. MDPHP is a potent stimulant research chemical. Ingestion can cause unpredictable, severe cardiovascular and neurological effects and is strictly prohibited.
Q5: Do you provide a Certificate of Analysis (CoA)?
A: Yes. We provide a comprehensive CoA—including HPLC, GC/MS, and NMR data—for every batch we sell. This guarantees the identity, purity, and safety of the compound.
Q6: How should I store MDPHP Freebase for long-term research?
A: For maximum longevity, store MDPHP freebase in an airtight, amber glass vial under an inert gas (like Argon) in a freezer set to -20°C. Keep away from direct sunlight, heat, and moisture. Freebases degrade much faster than salts if exposed to oxygen and light.
Q7: Is it legal to buy MDPHP in my country?
A: Legality varies drastically by country and is subject to change. Because it is an analog of MDPV, it is often controlled under analogue acts or specific substituted cathinone bans (including the US Federal Analogue Act). We cannot provide legal advice. It is your responsibility to research your local laws before placing an order.
