3-(Difluoromethoxy)benzeneboronic acid (CAS: 100687-29-4; Formula: C7H5BF2O2) is a specialized organoboron intermediate synthesized via lithiation of the corresponding aryl halide followed by boronation. It serves as a critical coupling partner in palladium-catalyzed cross-coupling reactions.
Store under inert atmosphere at temperatures below -20°C to prevent hydrolysis. Use appropriate PPE including nitrile gloves and eye protection due to potential skin irritation and toxicity upon ingestion.
