3-Acetylphenylboronic acid is widely used in organic synthesis, particularly in Suzuki-Miyaura cross-coupling reactions, where it serves as a key intermediate for constructing complex molecules. Its boronic acid group enables efficient coupling with aryl halides, making it valuable in the production of pharmaceuticals, agrochemicals, and advanced materials. Additionally, it is employed in the development of sensors and probes due to its ability to interact with diols and other functional groups, facilitating the detection of biological molecules. Its acetyl group further enhances its versatility by allowing derivatization for specific applications in drug discovery and material science.
