2,2′,4,5′,6-Pentachlorobiphenyl

Description:

2,2′,4,5′,6-Pentachlorobiphenyl, commonly referred to as PCB 118, is a member of the polychlorinated biphenyl (PCB) family, characterized by its biphenyl structure with five chlorine atoms substituted at specific positions. This compound is a colorless to light yellow solid at room temperature and is known for its hydrophobic nature, making it insoluble in water but soluble in organic solvents. PCB 118 exhibits high thermal stability and resistance to degradation, which contributes to its persistence in the environment. It has been utilized in various industrial applications, including electrical equipment, heat transfer fluids, and as a plasticizer. However, due to its toxicological profile, including potential carcinogenic effects and endocrine disruption, its production and use have been heavily regulated or banned in many countries. Environmental monitoring often detects PCB 118 in soil, sediments, and biota, raising concerns about its bioaccumulation and long-term ecological impacts. Proper handling and disposal are essential to mitigate its environmental and health risks.
