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.

Reaction progress analysis: Powerful tool for understanding suzuki-miyaura reaction and control of polychlorobiphenyl impurity

Cross coupling of unsaturated aryl or vinyl triflates/halides with aryl boronic acids using Pd as catalyst (Suzuki coupling) have become increasingly attractive for making the heterocoupled product (Ar-Ar′). However, most Pd cycle reactions produce some h

METHOD FOR SEPARATING AND CLEANING UP POLYHALOGENATED BIPHENYLS

The method for separating and cleaning up polyhalogenated biphenyls (PHBs) is characterized by comprising the following three steps: (1) the step of bringing a sample containing PHBs into contact with a fibrous activated carbon; (2) the step of washing the fibrous activated carbon with hexanes; and (3) the step of eluting PHBs from the fibrous activated carbon.

The influence of level and chlorine source on the formation of mono- to octa-chlorinated dibenzo-p-dioxins, dibenzofurans and coplanar polychlorinated biphenyls during combustion of an artificial municipal waste

The formation of polychlorinated dibenzo-p-dioxins (PCDDs), polychlorinated dibenzofurans (PCDFs) and the three coplanar polychlorinated biphenyls (pPCBs) was studied during labscale fludized bed combustion of eight artificial municipal solid waste (MSW) fuel mixtures. The level of chlorine as well as the chlorine source varies within the different fuel mixtures. Four different chlorine sources were studied, viz, an inorgnaic (NaCl) and three organic sources, pure PVC plastic and two products (floor and cable) and the total chlorine level varies between 0.28% and 1.1%. The experiments were performed in a 5 kW laboratory scale fluidized bed reactor. A correlation between the total chlorine in the fuel and the formation of the hepta- and octa-chlorinated PCDD/F homologues was found. However, the most important variable for changes in the PCDDs/Fs and pPCBs formation was disturbance in the combustion condition and not the variation in chlorine content of the fuel. Furthermore, no differences in formation between the chlorine sources could be seen.
