| | 3,3',4,4'-Tetrachlorobiphenyl Usage And Synthesis |
| Uses | 3,3'',4,4''-Tetrachlorobiphenyl is a polychlorinated biphenyl (PCB) congeners. | | Definition | ChEBI: A tetrachlorobiphenyl that is biphenyl in which the hydrogens at position 3 and 4 on each phenyl group are replaced by chlorines. | | Safety Profile | Poison by ingestion. An experimental teratogen. Experimental reproductive effects. Mutation data reported. When heated to decomposition it emits toxic fumes of Cl-. See also POLYCHLORINATED BIPHENYLS. | | Metabolic pathway | When 3,4,3',4' -tetrachlorobiphenyl (TCB) is orally
administered to rats, seven hydroxylated metabolites
are identified in the rat feces. The major metabolites
are 5-hydroxy-3,4,3',4' -TCB and 4-hydroxy-3,5,3',4' -
TCB. One further metabolite isolated is an oxepin,
existing in a state of equilibration with the 4',5' -
epoxide of the major metabolite, 4-hydroxy-3,5,3',4' -TCB. |
