Description

Benzoyl Fluoride, 4-(2-Butenyloxy)- (9Ci) is a specialized fluorinated aromatic compound that serves as a valuable building block in advanced organic synthesis. Its unique structure, featuring both a benzoyl fluoride moiety and an allyl ether side chain, makes it a versatile reagent for introducing fluorinated aromatic groups and for further functionalization via the alkene group. This compound is primarily utilized by research chemists and process development scientists in the pharmaceutical and agrochemical industries for the synthesis of novel active ingredients and complex intermediates. Its application is critical in the development of compounds where specific fluorine substitution patterns are required for enhanced biological activity or metabolic stability.

Application

• Pharmaceutical Intermediate: Key building block for the synthesis of fluorinated drug candidates, particularly in oncology and central nervous system (CNS) therapeutic areas.
• Agrochemical Synthesis: Used in the research and development of novel herbicides, fungicides, and insecticides where the fluorine atom improves efficacy and environmental persistence.
• Material Science Research: Serves as a monomer or precursor for specialty polymers and advanced materials with specific optical or electronic properties.
• Liquid Crystal & OLED Development: Employed in the synthesis of fluorinated aromatic cores for liquid crystal displays (LCDs) and organic light-emitting diodes (OLEDs).
• Cross-Coupling Reactions: Acts as an electrophilic coupling partner in palladium-catalyzed reactions (e.g., Suzuki, Stille) to create biaryl structures.
• Fluorination Reagent: Can be used as a source of the benzoyl fluoride group in nucleophilic aromatic substitution reactions to fluorinate other complex molecules.
