This compound is primarily used in organic synthesis, particularly in cross-coupling reactions such as Suzuki-Miyaura reactions, where it acts as a key intermediate for constructing complex organic molecules. Its boronate ester group facilitates the formation of carbon-carbon bonds, making it valuable in the development of pharmaceuticals, agrochemicals, and organic materials. Additionally, it is utilized in the synthesis of organic light-emitting diodes (OLEDs) due to its carbazole moiety, which contributes to electron transport and luminescent properties. Its role in polymer chemistry is also notable, as it aids in the creation of advanced materials with specific electronic or optical characteristics.
