What is 3,3',4,4'-TETRACHLOROBIPHENYL?

The Uses of 3,3',4,4'-TETRACHLOROBIPHENYL

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.
