2,3,3′,4,4′,5′,6-Heptachlorobiphenyl

Description:

2,3,3′,4,4′,5′,6-Heptachlorobiphenyl, with CAS number 74472-50-7, is a member of the polychlorinated biphenyl (PCB) family, which consists of biphenyl molecules with multiple chlorine substituents. This compound features seven chlorine atoms attached to the biphenyl structure, contributing to its stability and persistence in the environment. Heptachlorobiphenyl is characterized by its hydrophobic nature, low volatility, and resistance to degradation, which can lead to bioaccumulation in living organisms. It is typically found in industrial applications, although its use has been restricted or banned in many countries due to its toxicological effects, including potential carcinogenicity and endocrine disruption. The compound is lipophilic, meaning it tends to accumulate in fatty tissues, posing risks to wildlife and human health. Environmental monitoring often detects such compounds in soil, sediments, and biota, raising concerns about their long-term ecological impact. Proper handling and disposal are crucial to mitigate risks associated with exposure to this and similar substances.
