Methyl 3-fluoro-4-methyl-5-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)benzoate (CAS: 1907835-56-2) is a specialized boronic ester intermediate with molecular formula C15H20BFNO4. Synthesized via palladium-catalyzed borylation of methyl 3-fluoro-4-methyl-5-bromobenzoate, it serves as a critical building block for cross-coupling reactions in pharmaceutical manufacturing.
Store under inert atmosphere at -20°C to prevent hydrolysis. Handle in fume hoods using PPE due to potential respiratory irritation. Not approved for direct clinical use; strictly for industrial R&D and process chemistry.
