Description

4-Fluorostyrene (CAS No. 405-99-2) is a high-purity fluorinated aromatic compound with the molecular formula C₈H₇F and IUPAC name 1-ethenyl-4-fluorobenzene. This versatile monomer is widely used in polymer chemistry and materials science due to its reactive vinyl group and electron-withdrawing fluorine substituent. Our product is rigorously tested to ensure exceptional quality, with typical purity levels exceeding 98% (GC). Supplied as a clear, colorless to pale yellow liquid with a characteristic aromatic odor, it is packaged under inert atmosphere to maintain stability. 4-Fluorostyrene is particularly valuable for synthesizing fluorinated polystyrene derivatives, specialty polymers, and advanced materials with enhanced thermal and chemical resistance. Proper storage at 2-8°C under nitrogen is recommended to prevent polymerization. Suitable for research, pharmaceutical intermediates, and advanced material development.
