| synthesis and characterization of 2,3-dibromopropyl-2,4,6-tribromophenyl ether (dpte) and structurally related compounds evidenced in seal blubber and brain. | the unknown compound ubc-1 previously described as the major organobromine contamination in the blubber extract of a hooded seal (cystophora cristata) from the barents sea was identified as 2,3-dibromopropyl-2,4,6-tribromophenyl ether (dpte). dpte, which is the main component of the brominated flame retardant (bfr) bromkal 73-5 pe, was synthesized by electrophilic addition of bromine to allyl-2,4,6-tribromophenyl ether (ate). the chirality of dpte was proven by gas chromatographic enantioseparat ... | 2007 | 17396646 |
