4-Ethoxycarbonylphenylboronic acid (CAS: 1208-57-5, C11H13BO4) is a specialized boronic ester intermediate synthesized via palladium-catalyzed borylation of ethyl 4-bromobenzoate. It serves as a critical building block for Suzuki-Miyaura cross-coupling reactions in pharmaceutical and agrochemical manufacturing.
Store in a cool, dry place under inert atmosphere to prevent hydrolysis. Handle with appropriate PPE to avoid skin contact and inhalation; strictly avoid mixing with strong oxidizers or incompatible acids during processing.
