Used as a brominated sulfur-containing aromatic intermediate in organic synthesis. It is mainly applied in the preparation of organic semiconductor materials, OLED functional materials, conjugated polymers, and advanced aromatic heterocyclic compounds. The dibrominated dibenzothiophene structure provides two reactive bromine sites for further cross-coupling reactions such as Suzuki, Stille, and Buchwald-Hartwig coupling.
