2-Biphenylboronic 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 creation of complex organic molecules, including pharmaceuticals, agrochemicals, and materials. Its role as a boronic acid derivative makes it a key reagent in coupling aryl halides with aryl boronic acids, facilitating the synthesis of biaryl compounds. Additionally, it is employed in the development of sensors and molecular recognition systems due to its ability to interact with diols and other functional groups. Its applications also extend to polymer chemistry, where it aids in the modification and functionalization of polymers.
