2,2',3,3',5,5',6,6'-octachlorobiphenyl

Description:
2,2',3,3',5,5',6,6'-octachlorobiphenyl, commonly referred to as OC-8, is a synthetic organic compound belonging to the class of polychlorinated biphenyls (PCBs). It is characterized by its biphenyl structure, where eight chlorine atoms are substituted at various positions on the biphenyl rings. This compound is typically a colorless to light yellow solid with low volatility and high thermal stability, making it resistant to degradation. OC-8 is hydrophobic, exhibiting low solubility in water but high solubility in organic solvents, which contributes to its persistence in the environment. Due to its chemical stability and lipophilicity, it can bioaccumulate in living organisms, leading to potential toxic effects. PCBs, including OC-8, have been associated with various health risks, including endocrine disruption and carcinogenicity. As a result, the use of PCBs has been heavily regulated or banned in many countries. Environmental monitoring and remediation efforts are ongoing to address the legacy of PCB contamination in ecosystems.
