CAS 74472-42-7: PCB 158

Description: PCB 158, or polychlorinated biphenyl 158, is a member of the polychlorinated biphenyl (PCB) family, which consists of synthetic organic chemicals known for their industrial applications, particularly as coolants and insulating fluids in electrical equipment. PCB 158 is characterized by its complex structure, containing multiple chlorine atoms attached to biphenyl, which significantly alters its physical and chemical properties. This compound is typically a viscous liquid or solid, depending on temperature, and is known for its stability, low volatility, and resistance to degradation. However, PCBs, including PCB 158, are recognized for their environmental persistence and potential toxicity, leading to bioaccumulation in living organisms and concerns regarding human health. They can disrupt endocrine functions and have been linked to various adverse health effects. Due to these characteristics, the production and use of PCBs have been heavily regulated or banned in many countries. Proper handling and disposal of PCB 158 are crucial to mitigate its environmental impact and protect public health.
