Description

4-Bromo-3-Fluorostyrene 95% is a high-purity halogenated styrene derivative, a versatile and critical building block in advanced organic synthesis. Its value lies in providing a reactive vinyl group adjacent to bromine and fluorine substituents, enabling precise functionalization for complex molecule construction. This compound is essential for researchers and manufacturers in the pharmaceutical, agrochemical, and materials science industries, particularly for developing novel active ingredients and specialty polymers.

Application

• Pharmaceutical Intermediate: A key synthon for the development of novel drug candidates, especially in medicinal chemistry programs targeting CNS disorders and oncology.
• Agrochemical Synthesis: Used in the research and production of advanced pesticides and herbicides, where the bromo-fluoro motif can enhance biological activity and environmental stability.
• Liquid Crystal & OLED Material Precursor: Serves as a building block for synthesizing fluorinated aromatic compounds used in electronic display technologies and organic light-emitting diodes (OLEDs).
• Polymer & Resin Modification: Employed to introduce halogenated phenyl groups into polymer chains, modifying properties like flame retardancy, refractive index, and thermal stability for specialty plastics.
• Cross-Coupling Reactions: The bromine atom makes it an excellent substrate for palladium-catalyzed cross-coupling reactions (e.g., Suzuki, Heck, Sonogashira) to create complex biaryl and conjugated systems.
• Chemical Research & Development: A valuable reagent for academic and industrial R&D in exploring new synthetic methodologies and creating libraries of fluorinated compounds.
