2,4,2’,4’-Tetrabromodiphenyl ether(CAT: R023232) is a brominated flame retardant belonging to the polybrominated diphenyl ether (PBDE) family. Featuring four bromine atoms substituted at the 2 and 4 positions on each phenyl ring, it exhibits strong thermal stability and fire-retardant properties. This compound has been widely used in the manufacturing of plastics, textiles, electronics, and building materials to reduce flammability. However, due to its persistence, bioaccumulation, and potential toxicological effects, it is now subject to regulatory restrictions in many regions. It remains an important reference standard in environmental monitoring, toxicology studies, and research focused on the fate and impact of halogenated organic pollutants.
