Used as an intermediate in organic synthesis, particularly in cross-coupling reactions such as Suzuki and Ullmann reactions, to construct complex aromatic and heteroaromatic systems. Commonly employed in the development of organic semiconductors, pharmaceuticals, and functional materials due to its stable dibenzothiophene core and reactive bromine sites. Also utilized in the synthesis of ligands for catalysts and in materials science for creating conjugated polymers with tailored electronic properties.
