Introduction to Buy 4f-PiHP Powder

Buy 4f-PiHP Powder (4-Fluoro-alpha-pyrrolidinoisohexanophenone) is a highly potent, novel synthetic substituted cathinone belonging to the pyrrolidinophenone class. Structurally, it is the 4-fluoro analog of a-PiHP, featuring a fluorine atom substituted at the para-position of the phenyl ring, alongside the signature branched isohexanophenone alpha-carbon chain.

In neuropharmacological research, the addition of a fluorine atom is a critical modification. Fluorination typically increases a molecule’s lipophilicity and blocks specific hepatic enzymatic degradation pathways (C-F bond stability), significantly altering its metabolic stability and blood-brain barrier penetration kinetics compared to its non-fluorinated parent. In vitro, 4f-PiHP functions as a powerful dopamine-norepinephrine reuptake inhibitor (DNRI). Because extended-chain pyrrolidinophenones are notoriously unstable in their freebase form—often melting into an unmanageable, viscous resin at room temperature—we supply 4f-PiHP exclusively as a stable Hydrochloride (HCl) powder. This format ensures exceptional physical stability, precise measurability, and eliminates the severe hazards associated with handling sticky freebase oils. Note: This product is strictly intended for in-vitro research and analytical purposes only.

Key Features and Benefits – Buy 4f-PiHP Powder

• Fluorination SAR Modeling: 4f-PiHP provides researchers with a vital tool to study how para-fluorination alters the pharmacokinetic profile, lipophilicity, and DAT/NET affinity of branched-chain pyrrolidinophenones compared to non-fluorinated analogs (a-PiHP, a-PHP).
• DNRI Mechanism Research: Offers a potent reference standard for studying pure catecholamine reuptake inhibition at dopamine and norepinephrine transporters, contrasting its profile against releaser-type stimulants.
• Raw Powder Versatility: Supplied as a pure, raw powder, this format allows researchers to create precise, custom-concentration volumetric solutions tailored to unique in-vitro assay requirements.
• Enhanced Stability (HCl Salt): The HCl powder form is significantly more stable than freebase cathinone oils, preventing melting at room temperature and ensuring accurate micro-weighing and reproducible data.
• Aqueous Solubility: As an HCl salt, the powder dissolves readily in water and buffers, streamlining assay preparation.

Purity and Testing

We guarantee a purity level of ≥ 98% for our 4f-PiHP Powder. 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. Because pyrrolidinophenones are prone to degradation, special analytical care is taken to ensure minimal presence of oxidation products. Certificates of Analysis (CoA) and Safety Data Sheets (SDS) are provided upon request.

Frequently Asked Questions (FAQ)

Q1: What is 4f-PiHP?
A: 4f-PiHP (4-Fluoro-alpha-Pyrrolidinoisohexanophenone) is a synthetic substituted cathinone. It is the 4-fluoro analog of a-PiHP, featuring a fluorine atom on the phenyl ring and a branched isohexanophenone carbon chain. It acts primarily as a Dopamine-Norepinephrine Reuptake Inhibitor (DNRI), blocking the reabsorption of catecholamines in vitro.

Q2: What makes 4f-PiHP different from a-PiHP or a-PHP?
A: While all three are pyrrolidinophenones and potent DNRIs, 4f-PiHP features a fluorine atom at the 4-position of the phenyl ring. Fluorination is a critical bioisosteric replacement that increases lipophilicity and blocks certain metabolic pathways (due to the strong C-F bond), altering its metabolic stability and receptor kinetics. Additionally, like a-PiHP, it features a branched carbon chain, differing from the straight chain of a-PHP.

Q3: Why choose the HCl powder form over freebase?
A: Freebase synthetic cathinones with extended carbon chains are notoriously unstable, often melting into an unmanageable, viscous oil at room temperature, making accurate weighing impossible. The HCl powder form is stable, solid, and dry, allowing for precise micro-weighing and reproducible assay preparation.

Q4: Can 4f-PiHP Powder be consumed?
A: Absolutely NOT. 4f-PiHP is a potent CNS stimulant research chemical. It is sold strictly for in-vitro laboratory and analytical research. Ingestion can cause unpredictable, severe cardiovascular and psychological 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 mass of the compound.

Q6: Is it legal to buy 4f-PiHP in my country?
A: Legality varies drastically by country and is subject to change. Because it is an analog of scheduled cathinones like a-PHP, it is often controlled under analogue acts or specific NPS bans. We cannot provide legal advice. It is your responsibility to research your local laws regarding this compound before placing an order.

Q7: How should I store 4f-PiHP Powder for long-term research?
A: For maximum longevity, store 4f-PiHP powder 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.
