Description
3,3',4,4'-TETRACHLOROBIPHENYL, also known as a polychlorinated biphenyl (PCB) congener, is a chemical compound belonging to the class of biphenyls. In this compound, the hydrogens at positions 3 and 4 on each phenyl group are replaced by chlorine atoms, resulting in a tetrachlorinated structure. This specific congener is one of many possible PCB variants, each with different chlorine substitution patterns.
Uses
Used in Chemical Industry:
3,3',4,4'-TETRACHLOROBIPHENYL is used as a precursor in the synthesis of various chemical compounds for different applications, such as in the production of dyes, pigments, and other specialty chemicals. Its unique structure and properties make it a valuable intermediate in the chemical synthesis process.
Used in Electrical Industry:
In the past, 3,3',4,4'-TETRACHLOROBIPHENYL was used as a component in the manufacturing of certain types of electrical capacitors due to its dielectric properties. However, the use of PCBs, including this specific congener, has been largely phased out due to their environmental persistence and potential health risks.
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.
Check Digit Verification of cas no
The CAS Registry Mumber 32598-13-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 3,2,5,9 and 8 respectively; the second part has 2 digits, 1 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 32598-13:
(7*3)+(6*2)+(5*5)+(4*9)+(3*8)+(2*1)+(1*3)=123
123 % 10 = 3
So 32598-13-3 is a valid CAS Registry Number.
