Used in organic synthesis, particularly in Suzuki-Miyaura cross-coupling reactions to form carbon-carbon bonds. It serves as a key building block in the development of pharmaceuticals and agrochemicals, as well as advanced materials such as electronic components and luminescent compounds, where the boronic acid group enables selective transformations. Its chloro and pentyloxy substituents provide sites for further functionalization, making it valuable in the design of complex aromatic compounds. Commonly applied in medicinal chemistry for constructing biaryl systems found in bioactive molecules.
