This compound is primarily utilized in organic synthesis, particularly in cross-coupling reactions such as the Suzuki-Miyaura reaction. It serves as a key intermediate for constructing complex organic molecules, especially in the development of pharmaceuticals and advanced materials. Its boronic ester functionality allows for efficient coupling with aryl halides, enabling the formation of carbon-carbon bonds. This makes it valuable in the synthesis of polymers, OLED materials, and other electronic components where carbazole derivatives are essential. Additionally, it finds application in the preparation of organic semiconductors due to its electron-rich carbazole moiety, which enhances charge transport properties.
