2,2',4,6'-tetrachlorobiphenyl

Description:

2,2',4,6'-Tetrachlorobiphenyl, with the CAS number 68194-04-7, is a chlorinated biphenyl compound that belongs to the class of polychlorinated biphenyls (PCBs). This substance is characterized by its two connected phenyl rings, each substituted with chlorine atoms at specific positions, which significantly alters its chemical properties. It is typically a solid at room temperature and exhibits low volatility. The presence of chlorine atoms enhances its hydrophobicity, making it poorly soluble in water but more soluble in organic solvents. 2,2',4,6'-Tetrachlorobiphenyl is known for its stability and resistance to degradation, which contributes to its persistence in the environment. Due to its potential toxicity and bioaccumulation in living organisms, it has raised environmental and health concerns, leading to restrictions on its use and production in many countries. Its applications have historically included use as dielectric fluids in electrical equipment and as additives in various industrial processes. However, due to its environmental impact, its use has been largely phased out.
