(3-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, making it valuable in the production of pharmaceuticals, agrochemicals, and advanced materials. Its boronic acid group acts as a key intermediate, enabling the coupling of aryl or vinyl halides with arylboronic acids to create complex organic molecules. Additionally, it is employed in the development of bioactive compounds and in medicinal chemistry research for designing drug candidates. Its unique structure, combining chloro and cyano groups, also makes it useful in the synthesis of specialized polymers and functional materials.
