Find FXE purity test kits and reagent tests selected for fast substance identification and cleaner checking. CRITICAL WARNING: True FXE (3'-Fluoro-2-oxo-PCE, 3-FXE) may have NEVER been available on the recreational market. In April 2023, DrugsData.org revealed that ALL samples they previously identified as FXE actually contained 2F-NENDCK (CanKet, 2'-Fluoro-2-oxo-PCE), a positional isomer differing only by fluorine position on the phenyl ring. True 3-FXE and 2F-NENDCK are nearly impossible to distinguish without advanced analytical methods like NMR spectroscopy. Most user reports, dosage information, and effects attributed to FXE from 2017-2023 were likely describing 2F-NENDCK experiences. As of 2024-2025, some vendors claim to sell true 3-FXE, but independent laboratory verification is essential.
Drug purity testing kits come in 3 types: reagent tests, TLC and test strips. Use a multi-reagent kit to identify most common substances. Pair reagents with a TLC test kit to discover number and amount (%) of almost all ingredients. Use test strips to rule out fentanyl, nitazenes or xylazine.
