Used as a key intermediate in the synthesis of high-performance flame retardants due to its bromine-rich structure, which enhances thermal stability and fire resistance in polymers. Commonly incorporated into epoxy resins and printed circuit boards to meet stringent safety standards. Also serves as a building block in the development of specialty dyes and photo-sensitive materials for imaging applications. Its rigid biphenyl core supports use in advanced electronic materials where structural integrity and electronic properties are critical.
