Used in organic synthesis as a key intermediate for constructing complex molecules, particularly in Suzuki-Miyaura cross-coupling reactions. This reaction facilitates the formation of carbon-carbon bonds, enabling the creation of pharmaceuticals, agrochemicals, and advanced materials. Its boronic acid group is essential for coupling with aryl or vinyl halides, making it valuable in drug discovery and development. Additionally, it plays a role in the production of fluorescent dyes and organic electronic materials due to its aromatic structure. Its stability and reactivity make it a preferred choice in various research and industrial applications.
