(2-Formyl-3-methoxyphenyl)boronic acid is widely utilized in organic synthesis, particularly in Suzuki-Miyaura cross-coupling reactions. This reaction is essential for forming carbon-carbon bonds, making it valuable in the production of pharmaceuticals, agrochemicals, and advanced materials. The compound’s boronic acid group acts as a key intermediate, enabling the coupling of aryl or vinyl groups. Additionally, its formyl and methoxy substituents enhance its reactivity and selectivity in complex molecular constructions. It is also employed in the development of sensors and probes due to its ability to interact with diols and other biologically relevant molecules, making it useful in biochemical research and diagnostic applications.
