2,3′,4,4′,5,5′-Hexachlorobiphenyl

Description:
2,3′,4,4′,5,5′-Hexachlorobiphenyl, commonly referred to as PCB 153, is a polychlorinated biphenyl (PCB) compound characterized by the presence of six chlorine atoms attached to a biphenyl structure. This compound is part of a larger group of PCBs, which are synthetic organic chemicals known for their stability and resistance to degradation. PCB 153 is typically a colorless to light yellow solid at room temperature and is insoluble in water but soluble in organic solvents. Its chemical stability and hydrophobic nature contribute to its persistence in the environment, leading to bioaccumulation in the food chain. PCB 153 has been used in various industrial applications, including electrical equipment, heat transfer fluids, and as additives in plastics. However, due to its toxicological properties, including potential carcinogenic effects and endocrine disruption, its production and use have been heavily restricted or banned in many countries. Environmental monitoring and remediation efforts are ongoing to address the legacy of PCB contamination in ecosystems.
