2,3,4′-Trichlorobiphenyl

Description:

2,3,4′-Trichlorobiphenyl, with the CAS number 38444-85-8, is a chlorinated biphenyl compound that belongs to the class of polychlorinated biphenyls (PCBs). It is characterized by the presence of three chlorine atoms attached to the biphenyl structure, specifically at the 2, 3, and 4' positions. This compound is typically a colorless to pale yellow solid with low solubility in water but higher solubility in organic solvents. 2,3,4′-Trichlorobiphenyl exhibits hydrophobic properties, making it persistent in the environment and capable of bioaccumulation in living organisms. It is known for its thermal stability and resistance to degradation, which were some of the reasons PCBs were historically used in electrical equipment, heat exchangers, and other industrial applications. However, due to their environmental and health concerns, including potential carcinogenic effects, the use of PCBs has been heavily regulated or banned in many countries. Proper handling and disposal of such substances are crucial to mitigate their impact on human health and the environment.

2,3,4'-Trichlorobiphenyl is a polychlorinated biphenyl that has been shown to cause hepatotoxicity in animals. 2,3,4'-Trichlorobiphenyl is metabolized by cytochrome P450 1A1 to form reactive metabolites that bind covalently to cellular macromolecules. In vitro studies have shown that 2,3,4'-trichlorobiphenyl can be activated by mammalian cells and produce cytotoxic effects. It can also cause genetic mutations through the production of oxygen radicals and DNA adducts. The toxic effects of 2,3,4'-trichlorobiphenyl are increased when it is activated at high concentrations.
