2,2',3,4',5,5'-hexachlorobiphenyl

Description:
2,2',3,4',5,5'-Hexachlorobiphenyl, identified by its CAS number 51908-16-8, is a member of the polychlorinated biphenyl (PCB) family, which are synthetic organic chemicals known for their environmental persistence and potential toxicity. This compound features six chlorine atoms substituted on a biphenyl structure, which significantly alters its physical and chemical properties. It is typically a solid at room temperature and exhibits low volatility, making it resistant to degradation. The presence of multiple chlorine atoms enhances its hydrophobicity, leading to bioaccumulation in living organisms and potential biomagnification in food chains. 2,2',3,4',5,5'-Hexachlorobiphenyl is known for its stability and resistance to chemical reactions, which contributes to its longevity in the environment. However, its use has been restricted or banned in many countries due to concerns over its toxicity, including potential carcinogenic effects and endocrine disruption. Monitoring and remediation efforts are ongoing to address the environmental and health impacts associated with this and other PCB compounds.
