Used in organic synthesis as a building block for cross-coupling reactions, particularly in Suzuki-Miyaura coupling to construct biaryl compounds. Its boronic acid group enables bond formation with aryl halides, making it valuable in pharmaceutical and agrochemical research for developing complex aromatic structures. The pyrrole moiety adds heterocyclic character, useful in materials science for creating conjugated systems in organic electronics. Also employed in the synthesis of ligands and functionalized polymers.
