Used in organic synthesis as a boronic ester coupling partner in Suzuki-Miyaura cross-coupling reactions to construct biaryl or aryl-carbon frameworks. The methyl ester group allows for further functionalization, such as hydrolysis to the corresponding carboxylic acid or transformation into amides, alcohols, or other derivatives. Commonly employed in pharmaceutical and agrochemical research for building complex aromatic structures with high selectivity and yield. Its boronate ester group provides stability and ease of handling compared to boronic acids, making it suitable for iterative synthesis and library generation in drug discovery.
