CAS 69782-90-7: PCB 157

Description:PCB 157, or polychlorinated biphenyl 157, is a member of the polychlorinated biphenyl (PCB) family, which consists of synthetic organic chemicals known for their environmental persistence and potential toxicity. PCB 157 is characterized by its chlorinated biphenyl structure, which typically includes multiple chlorine atoms substituted on the biphenyl backbone. This compound is known for its hydrophobic properties, making it resistant to degradation in the environment. PCBs, including PCB 157, have been associated with various adverse health effects, including endocrine disruption and potential carcinogenicity. They can accumulate in the food chain, leading to higher concentrations in organisms at higher trophic levels. Due to their environmental and health risks, PCBs have been banned or heavily regulated in many countries since the late 20th century. The specific physical and chemical properties of PCB 157, such as melting point, boiling point, and solubility, can vary based on its degree of chlorination and structural isomers. Overall, PCB 157 exemplifies the concerns surrounding the use and disposal of chlorinated organic compounds.
