Atomfair 4-Fluorophenol p-Fluorophenol C6H5FO CAS 371-41-5

4-Fluorophenol (CAS No. 371-41-5) is a high-purity fluorinated aromatic compound with the molecular formula C6H5FO . This versatile intermediate is widely used in pharmaceutical, agrochemical, and material science research due to its reactive phenolic hydroxyl group and para-fluorine substitution. Available in crystalline form with ≥98% purity (GC), it exhibits excellent solubility in organic solvents like ethanol, methanol, and dimethyl sulfoxide (DMSO). Our 4-Fluorophenol is rigorously tested for impurities (HPLC, NMR) and packaged under inert gas to ensure stability. Ideal for nucleophilic substitution reactions, Suzuki couplings, and as a building block for advanced fluorinated compounds. SDS and analytical certificates are available…

Application

4-Fluorophenol serves as a key synthon in pharmaceutical development, particularly for fluorinated drug candidates targeting CNS disorders. It’s employed as a precursor for liquid crystal materials and agrochemicals due to its electron-withdrawing properties. Researchers also utilize it in PET radiotracer synthesis and as a modifier in polymer chemistry.
