N,N′-Ethylenebis(tetrabromophthalimide) is a brominated flame retardant used as an additive in plastics and synthetic rubbers, including polyolefins, HIPS, thermoplastic polyesters, and polycarbonates.National Institute of Environmental Health Sciences: Ethylenebis(tetrabromophthalimide), CASRN 32588-76-4, Review of Toxicological Literature, retrieved 13 May 2026. Characterized by high thermal and UV stability, it serves as an alternative to other brominated flame retardants. In 2014, the European Commission recommended monitoring EBTEBPI in foods.
Synthesis The synthesis of N,N′-ethylenebis(tetrabromophthalimide) is achieved by reacting tetrabromophthalic anhydride with ethylenediamine.
