2-FEA is a fluorinated amphetamine analogue carrying a fluorine atom on the alpha-ethyl chain at the 2-position, distinguishing it from the closely related 3-FEA (3-fluoroethamphetamine) and 4-FEA (4-fluoroethamphetamine) positional isomers. This fluorine substitution at the ethyl chain position — rather than the phenyl ring — produces a distinct physicochemical and analytical profile compared to ring-fluorinated amphetamine analogues such as 2-FA, 3-FA, and 4-FA. The ethyl chain fluorination confers increased metabolic stability at the fluorinated carbon position relative to non-fluorinated analogues, making 2-FEA a valuable tool compound for researchers studying the effects of aliphatic versus aromatic fluorine placement on amphetamine-class compound pharmacokinetics and transporter interaction profiles. 2-FEA pellets for sale at UltraRawz ship worldwide with discreet packaging from our US and Netherlands warehouses.

Each batch of 2-FEA pellets at ultrarawz.com/shop is HPLC-verified at ≥98% purity with batch-specific COA documentation. Related fluorinated amphetamine and phenethylamine research standards available at UltraRawz include 3-FEA, 4-FEA, 2-FA, 3-FA, 4-FA, and 2-FMA — providing a comprehensive fluoroamphetamine reference panel for comparative analytical and pharmacology research.

Chemical Identity & Classification

2-FEA Pellets carry CAS number 1270135-80-2, molecular formula C₉H₁₂FN, and molecular weight 153.19 g/mol. Systematic IUPAC designation: (±)-N-ethyl-1-(2-fluorophenyl)propan-2-amine. Laboratory synonyms: 2-fluoroethamphetamine, 2-FEA, ortho-fluoroethamphetamine. Structurally classified as a fluorinated secondary amine amphetamine — N-ethyl substituted primary amine with 2-fluorophenyl ring substitution. The 2-fluoro (ortho) substitution on the phenyl ring distinguishes 2-FEA from 3-FEA (meta-fluoro) and 4-FEA (para-fluoro) positional isomers — discrimination that is analytically critical as all three share the same molecular formula C₉H₁₂FN and molecular weight 153.19 g/mol. PubChem CID: 91723930. Protonated molecular ion [M+H]⁺: m/z 154.

Chemical & Physical Characteristics

2-FEA Pellets present as uniform compressed white to off-white pellets with each unit containing the specified mass of active compound. The active compound in bulk form is a white crystalline powder (hydrochloride salt). DMSO solubility: ≥10 mg/mL. Methanol and ethanol: freely soluble. Aqueous solubility: good (HCl salt form). logP: ~1.8 (calculated, free base). UV absorption: ~250–260 nm (fluorophenyl chromophore). The fluorine atom at the 2-position of the phenyl ring contributes to ¹⁹F NMR characterization — fluorine chemical shift approximately δ -115 to -118 ppm — providing an additional orthogonal identity confirmation tool alongside ¹H NMR and MS. Hygroscopicity: moderate; store with desiccant. The pellet format encapsulates the powder within a compressed matrix, reducing direct humidity and light exposure during handling compared to loose powder.

Purity & Analytical Verification

Production lots certify ≥98% purity by HPLC (C18 reverse-phase, acetonitrile/0.1% formic acid gradient, UV 254 nm, area normalization). Identity confirmed by: ¹H NMR (CDCl₃) — 2-fluorophenyl ortho-substitution pattern at δ 6.9–7.3 ppm with characteristic J-coupling from fluorine-proton coupling constants, distinguishing 2-FEA from 3-FEA and 4-FEA regioisomers. ¹⁹F NMR: diagnostic signal at δ ~-115 ppm confirming ortho-fluorophenyl substitution. GC-MS: molecular ion m/z 153; critical analytical note — all three FEA positional isomers share m/z 153, requiring FTIR, NMR, or authenticated reference co-elution for definitive isomer assignment. LC-MS/MS: [M+H]⁺ m/z 154; fragment m/z 110 (loss of N-ethylaminopropyl, 44 Da). Karl Fischer water content: <1.0% w/w. Pellet content uniformity tested (10-pellet sample, CV% <5%). COA available on request at support@ultrarawz.com.

Quality Control & Batch Integrity

Each production batch undergoes: HPLC purity assessment, ¹H and ¹⁹F NMR identity confirmation, GC-MS fragmentation verification, Karl Fischer water content determination, pellet weight uniformity testing (10-pellet CV%), and visual appearance inspection. Batch-specific lot numbers enable full traceability. The pellet content uniformity specification (CV% <5%) ensures consistent concentration accuracy across all pellets within a batch — a critical quality parameter for researchers using pellets as pre-measured dose units in assay work. Retained reference samples per batch support stability monitoring and reanalysis.

Safety, Handling & Laboratory Precautions

Handle exclusively within a properly ventilated fume hood. Required PPE: nitrile gloves (double-glove), lab coat, safety glasses, N95 respirator if crushing pellets for powder work. Monoamine-active compound — prevent dermal contact; verify glove integrity. Pellet handling: use clean forceps for pellet transfer — do not handle with bare fingers. For pellet dissolution: place pellets in dissolution vessel before adding solvent; do not dissolve through intact pellet coating if applicable. Anti-static forceps recommended for accurate pellet weighing. Spill containment: collect pellets in sealed container, absorb any powder with inert material, dispose per institutional chemical waste procedures. Emergency: if skin contact, wash with soap and water; if eye contact, flush 15 minutes, seek medical attention.

Packaging, Labeling & Storage

2-FEA Pellets are supplied in sealed amber glass vials with inert closures and desiccant packs, in discreet external packaging. Labels specify compound name, CAS 1270135-80-2, pellet count, mass per pellet, lot number, purity, and research use notice. Recommended storage: -20°C long-term; ≤25°C short-term (active use, max 2 weeks, desiccated, sealed). Amber glass provides UV protection — fluorinated amphetamines show photolability under prolonged UV exposure. Avoid polystyrene containers. Under recommended conditions, compound integrity maintained for the lot expiry period stated on the COA.

Intended Research Use & Market Positioning

2-FEA Pellets are positioned for: monoamine transporter pharmacology programs examining fluorine placement effects on DAT/SERT/NET binding affinity and selectivity across the fluoroamphetamine compound class; forensic toxicology laboratories developing LC-MS/MS screening methods for fluorinated amphetamine detection in biological matrices; SAR studies comparing ortho, meta, and para fluorophenyl ring substitution effects on amphetamine-class compound pharmacology; in-vitro metabolic stability research examining aliphatic versus aromatic fluorine effects on CYP-mediated biotransformation rates; and academic pharmacology programs developing fluorinated phenethylamine reference libraries.

Frequently Asked Questions

Q: What is the difference between 2-FEA, 3-FEA, and 4-FEA?
A: All three are positional isomers sharing molecular formula C₉H₁₂FN and MW 153.19 g/mol, but with the fluorine atom positioned at different locations on the phenyl ring (ortho/2-, meta/3-, para/4-positions respectively). They cannot be distinguished by GC-MS molecular ion alone — ¹⁹F NMR or FTIR fingerprint comparison with authenticated reference standards is required for definitive isomer assignment.

Q: Why use pellets instead of powder for 2-FEA?
A: Pellets eliminate individual weighing for standard-concentration assay work, reducing weighing error from static charge and hygroscopic moisture uptake. Each pellet contains a pre-certified mass of active compound, enabling rapid stock solution preparation without an analytical balance. Powder format is preferred when custom concentrations outside the pellet mass range are required.

Q: What purity does UltraRawz 2-FEA achieve?
A: ≥98% by HPLC area normalization. Batch-specific COA with HPLC chromatogram, NMR, and pellet uniformity data available on request.

Q: How do I dissolve 2-FEA pellets for stock solution preparation?
A: Place pellet(s) in dissolution vessel, add DMSO (preferred, ≥10 mg/mL effective concentration), vortex until fully dissolved. For aqueous work, methanol or acidified water also effective. Avoid crushing pellets in polystyrene containers.

Q: What storage conditions are required?
A: -20°C long-term in sealed amber glass with desiccant. ≤25°C short-term (max 2 weeks, sealed, desiccated). Protect from UV light.

Q: Is a COA available?
A: Yes, batch-specific COA including HPLC chromatogram, NMR data, and pellet uniformity data available on request. Contact support@ultrarawz.com.
