For research facilities seeking high purity 2-fluoroamphetamine powder for sale, the quality of reference standards directly impacts experimental validity. Whether your lab is in San Jose, Boston, or San Diego, understanding spectroscopy standards, isomer differentiation, and batch testing protocols is essential for reliable pharmacological research. This guide provides a technical breakdown of 2-FA specifications, comparative isomer analysis, and the quality documentation required for analytical-grade research.
Chemical Identity & Spectroscopy Standards
2-Fluoroamphetamine (2-FA) is a fluorinated amphetamine derivative with the IUPAC name 1-(2-fluorophenyl)propan-2-amine. Its molecular formula is C₉H₁₂FN with a molecular weight of 153.20 g/mol (free base). The hydrochloride salt has CAS number 1626-69-3, while the free base is registered as CAS 1716-60-5.
Spectroscopic Characterization
For research applications requiring rigorous compound verification, the following analytical methods are standard:
Gas Chromatography-Mass Spectrometry (GC-MS):
- Column: DB-1 MS (or equivalent), 30m x 0.25mm x 0.25µm
- Carrier gas: Helium at 1 mL/min
- Injector temperature: 280°C
- Oven program: 100°C for 1.0 min, ramp to 300°C at 12°C/min, hold 9.0 min
- Injection volume: 1 µL with split ratio 20:1
- Mass scan range: 30-550 amu
Infrared (IR) Spectroscopy:
- FTIR with diamond ATR accessory
- Spectral range: 4000-400 cm⁻¹
- Key characteristic: C-F stretching vibrations observed around 1232 cm⁻¹ for 2-FA
Storage Conditions: Research-grade 2-FA powder should be stored at -20°C for long-term stability, in a cool, dry place away from direct sunlight. For working solutions, DMF, DMSO, and ethanol are suitable solvents.
2-FA vs 3-FA vs 4-FA: Isomer Differentiation
The fluorinated amphetamine analogs exist as three regioisomers, differentiated by the position of the fluorine atom on the phenyl ring. Understanding these differences is critical for researchers evaluating comparative pharmacological studies.
Comparative Pharmacological Data
A 2025 peer-reviewed study investigating these isomers in rodent models reported:
- Potency rank order: 2-FMA > methamphetamine > 3-FMA = 3-FA = 2-FMA > 4-FMA
- Peak effects: 2-FA, 3-FA, and 3-FMA produced peak locomotor effects comparable to methamphetamine (5,905-7,758 counts)
- Discriminative stimulus: All fluorinated compounds elicited dose-dependent full substitution for methamphetamine, with comparable potencies (ED₅₀ values 0.32-0.71 mg/kg)
The study concluded that these analogs may have a potential for abuse comparable to methamphetamine, highlighting the importance of proper handling protocols in research settings.
Quality Standards: What to Look For
When sourcing analytical grade 2-FA Philadelphia or other locations, verify the following quality documentation:
Certificate of Analysis (COA) Requirements
- Purity verification: ≥98% by HPLC is the industry standard for research-grade material
- Batch-specific testing: Each batch should have its own COA, not a generic template
- Third-party laboratory confirmation: Independent HPLC and MS verification
- Impurity profile: All detected impurities should be characterised
- Solubility data: Confirmation of solubility in standard solvents (DMF, DMSO, ethanol)
Quality Red Flags
- COAs without batch-specific referencing or chromatogram data
- Purity figures quoted as rounded “≥95%” without measured values
- No mass spectrometry confirmation matching the expected molecular weight
- In-house testing only, with no third-party verification

Research Applications & Use Cases
2-FA is primarily used in pharmacological research to investigate its stimulant properties and interactions with monoamine transporters. The compound acts as a monoamine releasing agent, primarily affecting the dopamine and norepinephrine systems.
Mechanism of Action
2-FA’s proposed mechanism involves:
- Transporter uptake: Entry into presynaptic neurons via DAT and NET
- VMAT2 inhibition: Disruption of monoamine packaging into synaptic vesicles
- Kinase activation: PKC and CaMKII activation
- Reverse transport: Phosphorylation-induced conformational change causing efflux of dopamine and norepinephrine
- Transporter internalisation: RhoA-mediated reduction in reuptake capacity
This mechanism is analogous to classical amphetamine, making 2-FA a valuable tool for studying catecholaminergic signaling pathways.
Common Research Scenarios
The Comparative Researcher: Evaluating positional isomer effects on monoamine transporter activity. 2-FA, 3-FA, and 4-FA exhibit different potencies and efficacies, making them suitable for structure-activity relationship studies.
The Analytical Lab: Requiring high-purity reference standards for LC-MS/MS method development. Research-grade 2-FA with ≥98% purity is essential for creating reliable calibration curves.
The Regional Sourcing Lab: Facilities in the San Francisco Bay Area, Boston, and San Diego benefit from suppliers with established shipping infrastructure. AK Scientific, for example, stocks 2-FA hydrochloride and ships from the SF Bay Area via FedEx, UPS, or DHL.
Conclusion
Sourcing high purity 2-fluoroamphetamine powder for sale requires careful attention to spectroscopy standards, isomer differentiation, and batch-specific quality documentation. The 2025 peer-reviewed data on fluorinated amphetamine analogs provides valuable context for comparative research, highlighting the distinct pharmacological profiles of 2-FA, 3-FA, and 4-FA. Always insist on ≥98% HPLC purity, batch-specific COAs with independent laboratory verification, and proper storage at -20°C for long-term stability.
