(5-Fluoro-2-formylphenyl)boronic acid is primarily used in organic synthesis, particularly in Suzuki-Miyaura cross-coupling reactions. This reaction enables the formation of 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, facilitating the coupling of aryl or vinyl groups. Its formyl group also allows for further functionalization, making it a versatile building block in the synthesis of complex organic molecules. Additionally, it finds applications in the development of sensors and molecular probes due to its ability to interact with diols and other biologically relevant molecules.
