Used as a key building block in Suzuki-Miyaura cross-coupling reactions, enabling the synthesis of complex aromatic compounds for pharmaceuticals and agrochemicals. Its protected boronic acid group enhances stability and handling, making it ideal for multi-step organic syntheses. Commonly employed in the preparation of functionalized biaryl systems and conjugated materials for optoelectronics. Also utilized in the development of sensors and molecular recognition systems due to its ability to form ester-linked networks with diols.
