Brominated dibenzodioxins (PBDDs) may be widely dispersed in the environment, arising from the oxidative ring closure of fire retardant brominated biphenyl ethers, from the combustion of other bromine containing materials, from the use of brominated phenols as synthetic intermediates, and from other routes analogous to those leading to formation of the polychlorinated dibenzodioxins (PCDDs). In order to monitor possible environmental contamination by highly toxic PBDDs, authentic analytical chemical standards of these compounds must be available. Therefore, dibenzo-p-dioxin has been brominated under standard electrophilic conditions to yield mono through octabromodibenzodioxin. The GC retention indices (RI) for thirteen products have been measured and correlated with the retention indices calculated for the corresponding chlorodibenzodioxins. Mass spectra for the eight major congeners are reported.
