Used in organic synthesis, particularly in Suzuki-Miyaura cross-coupling reactions, as a versatile building block for constructing conjugated organic molecules. Its vinylboronate ester group enables efficient carbon-carbon bond formation with aryl or vinyl halides, making it valuable in the development of pharmaceuticals, agrochemicals, and advanced materials such as organic semiconductors and liquid crystals. The methyl ester functionality allows for further chemical modifications, enhancing its utility in multi-step syntheses.
