CAS 34883-43-7: PCB 8

Description: PCB 8, or polychlorinated biphenyl 8, is a member of the polychlorinated biphenyl (PCB) family, which consists of synthetic organic chemicals known for their industrial applications and environmental persistence. Characterized by the presence of multiple chlorine atoms attached to biphenyl, PCB 8 typically exhibits a complex structure that influences its chemical properties, such as hydrophobicity and thermal stability. This compound is known for its resistance to degradation, leading to bioaccumulation in the environment and living organisms. PCBs, including PCB 8, have been associated with various adverse health effects, including endocrine disruption and potential carcinogenicity. Due to these concerns, the production and use of PCBs have been heavily regulated or banned in many countries. PCB 8 can be found in older electrical equipment, hydraulic fluids, and other industrial applications. Its environmental monitoring is crucial for assessing contamination levels and understanding its impact on ecosystems and human health.
