Used in organic synthesis, particularly in Suzuki-Miyaura cross-coupling reactions, to create complex organic compounds. It serves as a key intermediate in the production of pharmaceuticals, agrochemicals, and organic materials. Its boronic acid group enables efficient coupling with aryl halides, facilitating the formation of carbon-carbon bonds. Also employed in the development of organic light-emitting diodes (OLEDs) and other electronic materials due to its carbazole moiety, which enhances charge transport properties.
