Widely used in Suzuki-Miyaura cross-coupling reactions, this compound serves as a key building block for constructing biaryl systems in pharmaceutical and agrochemical synthesis. The boronate ester group readily participates in palladium-catalyzed couplings with aryl halides, enabling efficient formation of carbon-carbon bonds. Its tert-butyl ester functionality remains stable under coupling conditions and can be deprotected later to yield carboxylic acid derivatives. This makes it valuable in multi-step synthesis of complex organic molecules, especially in drug discovery and materials science where precise molecular architecture is critical.
