Used in organic synthesis as a building block for Suzuki-Miyaura cross-coupling reactions, enabling the formation of carbon-carbon bonds in the preparation of complex organic molecules, particularly in pharmaceutical and materials chemistry. Its structure allows for the introduction of fluorenone-derived moieties into larger conjugated systems, making it valuable in the development of organic semiconductors, fluorescent dyes, and bioactive compounds. The boronic acid group facilitates palladium-catalyzed coupling with aryl halides, offering versatility in constructing functionalized aromatic frameworks.
