Cas no 1073339-03-3 (3-Bromo-5-ethoxyphenylboronic Acid Pinacol Ester)
3-Bromo-5-ethoxyphenylboronic acid pinacol ester is a boronic ester derivative commonly employed in Suzuki-Miyaura cross-coupling reactions. The bromo and ethoxy substituents enhance its reactivity and selectivity in palladium-catalyzed transformations, making it valuable for constructing complex aryl-aryl bonds. The pinacol ester group improves stability, facilitating handling and storage compared to free boronic acids. This compound is particularly useful in pharmaceutical and materials science research, where controlled functionalization of aromatic systems is required. Its well-defined structure ensures consistent performance in synthetic applications, while the bromine moiety allows for further derivatization via halogen exchange or metal-halogen exchange reactions.
