PCB 74

Description:
PCB 74, or polychlorinated biphenyl 74, is a member of the polychlorinated biphenyl (PCB) family, which consists of synthetic organic chemicals with varying degrees of chlorination. Characterized by its biphenyl structure, PCB 74 contains multiple chlorine atoms attached to the biphenyl backbone, influencing its physical and chemical properties. This compound is typically a colorless to light yellow solid or viscous liquid, depending on its specific formulation and temperature. PCBs, including PCB 74, are known for their chemical stability, hydrophobicity, and resistance to degradation, which contribute to their persistence in the environment. They are also lipophilic, leading to bioaccumulation in living organisms. PCB 74 has been utilized in various industrial applications, including electrical equipment and heat transfer fluids, but its use has been heavily restricted or banned in many countries due to its toxicological effects, including potential carcinogenicity and endocrine disruption. Environmental monitoring and remediation efforts are ongoing to address the contamination associated with PCBs, including PCB 74.
