CAS 70362-50-4: PCB 81

Description:PCB 81, or polychlorinated biphenyl 81, is a member of the polychlorinated biphenyl (PCB) family, which consists of synthetic organic chemicals composed of carbon, hydrogen, and chlorine atoms. PCB 81 is characterized by its biphenyl structure, where chlorine atoms are substituted at specific positions on the biphenyl rings. This compound is known for its hydrophobic nature, making it persistent in the environment and capable of bioaccumulation in living organisms. PCBs, including PCB 81, are typically colorless to light yellow solids or oils and are non-flammable. They exhibit thermal stability and resistance to degradation, which contributes to their environmental persistence. PCB 81 has been studied for its potential toxicological effects, including endocrine disruption and neurotoxicity, raising concerns regarding human health and ecological impacts. Due to these characteristics, PCBs have been banned or heavily regulated in many countries, and their presence in the environment is monitored to mitigate risks associated with exposure.
