This compound is primarily used in organic synthesis, particularly in Suzuki-Miyaura cross-coupling reactions. It serves as a key intermediate for constructing complex organic molecules, especially in the development of pharmaceuticals and advanced materials. Its boronic acid group enables efficient coupling with aryl halides, making it valuable in creating carbon-carbon bonds. Additionally, it finds application in the synthesis of organic electronic materials, such as OLEDs, due to its carbazole moiety, which contributes to charge transport properties. Its role in medicinal chemistry includes the development of bioactive compounds and drug candidates.
