Comments

"Commercial octabromodiphenyl ether is a mixture of approximately 11% pentabromodiphenyl ether/hexabromodiphenyl ether, 44% heptabromodiphenyl ether, 31-35% octabromodiphenyl ether, 10% nonabromodiphenyl ether, and 0.5% decabromodiphenyl ether. On the basis of the chemical structure, there are 12 possible isomers of octabromodiphenyl ether." [HSDB] Dermal absorption is estimated at 4.5%; [ToxPlanet: European Commission] See "Decabromodiphenyl ether."
