Alpha PHP (a-PHP)

Buy Alpha PHP Research Chemical Online – USA, Europe & Worldwide

The substituted cathinone class of research chemicals has garnered significant attention in neuropharmacology due to their structural similarity to naturally occurring cathinone and their potent interactions with monoamine transporters. Alpha PHP (a-PHP, α-Pyrrolidinohexanophenone) is a synthetic cathinone derivative characterized by a pyrrolidine ring attached to the nitrogen, a hexyl chain at the alpha position, and a beta-keto group. This specific structural configuration—a secondary amine with a pyrrolidine ring, a six-carbon alpha chain, and a ketone at the beta position—confers distinct pharmacological properties as a monoamine reuptake inhibitor.

The compound is registered under CAS number 3415-86-6, providing unambiguous chemical identification for research documentation. For researchers investigating the molecular mechanisms of monoamine transporter interactions and the structure-activity relationships of synthetic cathinones, Alpha PHP offers a valuable tool to explore how pyrrolidine ring substitution and alpha-chain length influence dopamine (DAT), norepinephrine (NET), and serotonin (SERT) transporter binding and reuptake inhibition.

Purity & Testing

Reproducibility in monoamine transporter research and neuropharmacology depends critically on compound purity. Impurities—particularly other cathinone isomers, synthetic intermediates, or degradation products—can produce false-positive signals in transporter binding assays or confound functional reuptake measurements. That is why 99% pure Alpha PHP from RChems EU is subjected to a multi-laboratory quality control workflow:

1. High-Performance Liquid Chromatography (HPLC-DAD): Quantitative analysis at multiple wavelengths. Minimum acceptance criterion: ≥99.0% peak area purity.
2. Liquid Chromatography-Mass Spectrometry (LC-MS): Confirms molecular ion [M+H]⁺ = 246.2 for the 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 beta-keto phenethylamine backbone, pyrrolidine ring, and hexyl chain. Any spectral deviation—particularly signals indicative of incorrect substitution or ring structure—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.

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 Alpha PHP for research, you receive a compound that performs consistently from order to order.

6. Can you ship Alpha PHP to my country (USA, UK, Germany, Australia, Canada)?

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

7. How should I store Alpha PHP after delivery?

Store Alpha PHP in a tightly sealed, amber glass vial at room temperature (20–25°C) in a desiccator, protected from light and moisture. For long-term storage (>6 months), refrigeration at 4°C under inert atmosphere (argon or nitrogen) is recommended. Always allow the sealed container to reach room temperature before opening to prevent condensation. Store in a cool, dry, well-ventilated area away from heat and direct sunlight.

8. What is the difference between Alpha PHP and alpha-PVP?

The key structural difference is the alpha-chain length:

• alpha-PVP has a pentyl chain (5 carbons)
• Alpha PHP has a hexyl chain (6 carbons)

In monoamine transporter research, extending the alpha-chain length from pentyl to hexyl can alter binding affinity, selectivity for DAT vs. NET vs. SERT, and metabolic stability. Comparing these two compounds allows researchers to systematically investigate the impact of alpha-chain lengthening on pyrrolidinophenone pharmacology.

9. What is the significance of the pyrrolidine ring in Alpha PHP?

The pyrrolidine ring (a five-membered cyclic secondary amine) is characteristic of the pyrrolidinophenone subclass of cathinones. This structural feature:

• Confers higher potency compared to acyclic amine analogs
• Affects transporter binding kinetics and selectivity
• Influences metabolic stability (the pyrrolidine ring can undergo ring-opening or N-dealkylation)
• Distinguishes pyrrolidinophenones from other cathinone derivatives

Comparing Alpha PHP with acyclic analogs (such as N-ethylhexedrone) allows researchers to investigate the impact of the cyclic pyrrolidine ring on cathinone pharmacology.

10. What is the mechanism of action of Alpha PHP in research models?

In in vitro research models, Alpha PHP acts primarily as a monoamine reuptake inhibitor, blocking the dopamine transporter (DAT) and norepinephrine transporter (NET) with high potency, while showing lower affinity for the serotonin transporter (SERT). This DAT/NET selectivity profile is characteristic of pyrrolidinophenone cathinones. Researchers determine the specific mechanism using functional uptake inhibition assays in transfected cell lines or synaptosomal preparations.

11. 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.
