Widely used in Suzuki-Miyaura cross-coupling reactions, this compound serves as a key reagent for forming carbon-carbon bonds in organic synthesis. Its stability and reactivity make it ideal for constructing biaryl structures, commonly found in pharmaceuticals, agrochemicals, and advanced materials. The iodine moiety allows further functionalization or coupling, while the pinacol ester group enhances shelf life and handling compared to the parent boronic acid. It is frequently employed in drug discovery and the development of conjugated systems for optoelectronic applications.
