4-Bromo-trans-β-styrylboronic acid pinacol ester (Cat No.: M073160) is an organoboron compound featuring a trans-styryl backbone with a bromo substituent at the para position and a boronic acid protected as a pinacol ester. This crystalline solid is commonly used in Suzuki–Miyaura cross-coupling reactions to construct substituted styrenes and extended π-conjugated systems. Its stability and functional group compatibility make it valuable in pharmaceutical development, material science, and organic electronics for synthesizing complex molecules, ligands, and functionalized aromatic and alkenyl derivatives.
