Used in organic synthesis as a key building block for Suzuki-Miyaura cross-coupling reactions, enabling the formation of carbon-carbon bonds in pharmaceutical and agrochemical intermediates. Its vinylboronic acid structure allows for selective transformations in conjugated systems, making it valuable in the preparation of styrene derivatives and functionalized aromatic compounds. The carboxylic acid group provides a handle for further derivatization or conjugation, useful in materials science and bioconjugation applications. Often employed in the development of sensors and functional polymers due to its dual reactivity.
