CAS 35065-28-2: PCB 138

Description: PCB 138, or polychlorinated biphenyl 138, is a member of the polychlorinated biphenyl (PCB) family, which consists of synthetic organic chemicals composed of carbon, hydrogen, and chlorine atoms. It is characterized by its biphenyl structure, where two benzene rings are connected by a single bond, with chlorine atoms substituted at specific positions on the rings. PCB 138 typically contains a total of six chlorine atoms, which influence its physical and chemical properties, such as stability, hydrophobicity, and resistance to degradation. This compound is known for its high thermal stability and low volatility, making it useful in various industrial applications, including electrical equipment and heat transfer fluids. However, PCBs, including PCB 138, are recognized as environmental pollutants due to their persistence in the environment and potential to bioaccumulate in living organisms. They have been associated with various health risks, including endocrine disruption and carcinogenic effects, leading to regulatory restrictions on their use and disposal.
