Used primarily as an intermediate in organic synthesis, especially in the preparation of functionalized dibenzofurans for pharmaceuticals and advanced materials. It serves as a building block in cross-coupling reactions, such as Suzuki and Ullmann reactions, enabling the formation of biaryl structures found in bioactive molecules and optoelectronic compounds. Also employed in the development of ligands for catalysts and in the synthesis of polycyclic aromatic systems for use in organic semiconductors and fluorescent dyes.
