Used in organic synthesis as a building block for pharmaceuticals, particularly in Suzuki-Miyaura cross-coupling reactions to construct biaryl compounds. Its boronic acid group enables efficient carbon-carbon bond formation, making it valuable in drug discovery and development. Commonly applied in the synthesis of kinase inhibitors and other bioactive molecules targeting cancer and inflammatory diseases. Stable and compatible with a range of functional groups, it supports late-stage functionalization in medicinal chemistry.
