3‑FA (3‑Fluoroamphetamine) — full chemical name: 3‑Fluoro‑1‑phenylpropan‑2‑amine — is a synthetic stimulant belonging to the substituted amphetamine / phenethylamine class, closely related to amphetamine, methamphetamine, 2‑FA, and 4‑FA. Its defining structural features are:

Pharmacologically, 3‑FA acts as a potent releasing agent and reuptake inhibitor of dopamine and norepinephrine, with moderate activity at serotonin transporters. It triggers rapid neurotransmitter release and blocks reuptake, producing powerful stimulant effects, strong reinforcing properties, and increased locomotor activity in research models. Compared to unsubstituted amphetamine, 3‑FA is approximately 2–2.5 times more potent and has better metabolic stability. Compared to 4‑FA, the 3‑fluoro isomer offers a more balanced ratio of dopamine to serotonin activity, resulting in a more predictable, less serotonergic profile — preferred for precise research applications.

It appears as brilliant white to off‑white fine crystalline powder, dry, free‑flowing, non‑hygroscopic, and soluble in organic solvents like methanol, ethanol, DMSO, and acetone; slightly soluble in water. This physical form allows for extremely accurate weighing, easy solution preparation, and reliable dosing in experimental settings.

Premium High Purity ≥99%: Highest grade available; eliminates impurity interference, ensures 100% accurate research results.

Enhanced Potency: ~2–2.5x vs. amphetamine; strong activity at dopamine & norepinephrine transporters.

Fluorination Advantage: 3‑fluoro substitution resists metabolism — effects last 4–6+ hours; ideal for stimulation studies.

Balanced Isomer Profile: 3‑fluoro isomer offers balanced DAT/NET/SERT activity, cleaner effects than 2‑FA or 4‑FA; better for precise research.

Primary Amine Structure: Classic amphetamine backbone — perfect for structure‑activity relationship research; direct comparison to parent compounds.

Defined Transporter Selectivity: Higher DAT/NET ratio than 4‑FA — more dopaminergic, less serotonergic; valuable for studying neurotransmitter balance.

Fine Crystalline Powder: Pure, dry, free‑flowing — easy to weigh, measure, and prepare solutions; no clumping or moisture issues.

Freshly Synthesized & Purified: Produced to exact standards, shipped fresh — no degradation, no loss of activity.

Consistent Quality: Every batch tested and verified — same composition, same potency every time.

Secure Packaging: Vacuum‑sealed, airtight, light‑protected — remains stable for 24+ months.

Discreet Shipping: Plain packaging, no labels, no description — undetected delivery worldwide.

Flexible Quantities: From small 1g samples to large bulk — suitable for all research scales.

Q1: How does 3‑FA compare to amphetamine or 4‑FA?

Stronger, more stable, and better balanced. Compared to unsubstituted amphetamine, 3‑FA is ~2–2.5x more potent and resists breakdown longer. Compared to 4‑FA, it has a more favorable ratio of dopamine to serotonin activity — producing stronger stimulant effects with less unwanted serotonergic action, making it more suitable for studying dopaminergic pathways specifically.

Q2: What makes 3‑FA unique for medicinal chemistry research?

Its 3‑fluoro substitution on the primary amphetamine backbone is the defining feature. This precise modification creates a molecule with enhanced potency, metabolic stability, and defined transporter selectivity. It is the perfect tool to study how fluorine position alters binding, release, and inhibition — essential for understanding structure‑activity relationships in phenethylamine and amphetamine design.

Q3: What purity and form do you supply?

Premium grade ≥99% — brilliant white fine crystalline powder. Tested via HPLC, GC‑MS, and NMR to confirm identity and purity. Dry, free‑flowing, non‑hygroscopic powder — no additives, no cutting agents, no residual solvents. Consistent quality required for accurate, publishable research.

Q4: Is it legal to buy/own in USA, Europe & Canada?

NO — fully illegal & controlled everywhere. 3‑FA is classified as a controlled substance / illegal stimulant analog / new psychoactive substance in USA, all EU countries, Canada, and nearly all nations. Possession, sale, or use is a serious crime — long prison sentences apply. Sold only as “research chemical” — research exemption does not apply. You are fully responsible for compliance with all laws.

Q5: What research is 3‑FA best suited for?

Widely used in: dopamine/norepinephrine transporter pharmacology, stimulant research, addiction science, reinforcement studies, structure‑activity relationship (SAR) research, medicinal chemistry, neurochemistry, and behavioral pharmacology. It is the reference compound for 3‑fluoro‑substituted primary amphetamine derivatives.
