(2-Chloro-5-cyanophenyl)boronic acid is widely used in organic synthesis, particularly in Suzuki-Miyaura cross-coupling reactions. This reaction is essential for forming carbon-carbon bonds, enabling the synthesis of complex organic molecules, including pharmaceuticals, agrochemicals, and advanced materials. Its boronic acid group acts as a key intermediate, facilitating the coupling with aryl halides in the presence of a palladium catalyst. Additionally, it is employed in the development of sensors and probes due to its ability to interact with diols and other functional groups, making it useful in biochemical and analytical applications. Its unique structure also allows for modifications in drug discovery, aiding in the creation of targeted therapeutic agents.
