Used as a key intermediate in the synthesis of pharmaceutical compounds, particularly in the development of kinase inhibitors for cancer treatment. Its boronic acid functional group enables Suzuki-Miyaura cross-coupling reactions, making it valuable in constructing biaryl structures found in active pharmaceutical ingredients. It is also employed in the preparation of protease inhibitors and other bioactive molecules due to its ability to form stable bonds with various electrophilic partners. Commonly utilized in medicinal chemistry for lead optimization and library synthesis in drug discovery programs.
