Used as a key intermediate in organic synthesis, particularly in Suzuki-Miyaura cross-coupling reactions for constructing biaryl frameworks. Its boronic acid functionality enables efficient carbon-carbon bond formation, making it valuable in the development of organic electronic materials such as OLEDs and semiconducting polymers. Commonly employed in the synthesis of conjugated molecules for optoelectronic devices due to the combined electron-transport properties of the carbazole and biphenyl moieties. Also utilized in pharmaceutical research for building complex aromatic structures with potential bioactivity.
