Pentabromodiphenyl ether (also known as pentabromodiphenyl oxide) is a brominated flame retardant which belongs to the group of polybrominated diphenyl ethers (PBDEs). Because of their toxicity and persistence, their industrial production is to be eliminated under the Stockholm Convention , a treaty to control and phase out major persistent ...
Polybrominated diphenyl ethers or PBDEs, are a class of organobromine compounds that are used as flame retardants.Like other brominated flame retardants, PBDEs have been used in a wide array of products, including building materials, electronics, furnishings, motor vehicles, airplanes, plastics, polyurethane foams, [1] and textiles.
Octabromodiphenyl ether (octaBDE, octa-BDE, OBDE, octa, octabromodiphenyl oxide, OBDPO) is a brominated flame retardant which belongs to the group of polybrominated diphenyl ethers (PBDEs). Composition, uses, and production
Decabromodiphenyl ether (also referred to as decaBDE, DBDE, BDE-209) is a brominated flame retardant which belongs to the group of polybrominated diphenyl ethers (PBDEs). It was commercialised in the 1970s and was initially thought to be safe, [ 3 ] [ 4 ] but is now recognised as a hazardous and persistent pollutant.
Decabromodiphenyl ethane is a chemical compound used as a brominated flame retardant. It was commercialised in the 1990s as an alternative for decabromodiphenyl ether, [1] following safety concern over that compound. The two molecules are chemically very similar, which gives them a similar application profile.

1,1,2,2-Tetrabromoethane, or simply tetrabromoethane (TBE), is a halogenated hydrocarbon, chemical formula C 2 H 2 Br 4.Although three bromine atoms may bind to one of the carbon atoms creating 1,1,1,2-tetrabromoethane this is not thermodynamically favorable, so in practice tetrabromoethane is equal to 1,1,2,2-tetrabromoethane, where each carbon atom binds two bromine atoms.
Dibromine pentoxide is the chemical compound composed of bromine and oxygen with the formula Br 2 O 5. It is a colorless solid that is stable below −20 °C. It has the structure O 2 Br−O−BrO 2, the Br−O−Br bond is bent with bond angle 121.2°. Each BrO 3 group is pyramidal with the bromine atom at the apex. [2]
