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 advanced materials. Its role as a boronic acid derivative makes it a valuable reagent for constructing biphenyl structures, which are common in many active pharmaceutical ingredients. Additionally, it is employed in the development of sensors and catalysts due to its ability to interact with various organic and inorganic compounds. Its stability and reactivity under mild conditions further enhance its utility in research and industrial applications.
