2,2',3,3',4,4',6-heptachlorobiphenyl

Description:
2,2',3,3',4,4',6-heptachlorobiphenyl, identified by CAS number 52663-71-5, 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 chemical stability and lipophilicity. It is a colorless to light yellow solid at room temperature and is insoluble in water but soluble in organic solvents. Due to its chlorinated nature, 2,2',3,3',4,4',6-heptachlorobiphenyl exhibits high thermal stability and resistance to degradation, making it persistent in the environment. This compound has been associated with various environmental and health concerns, including potential toxicity and bioaccumulation in living organisms. Its use has been restricted or banned in many countries due to its environmental impact and potential to disrupt endocrine systems. As with other PCBs, it is important to handle this substance with care, following appropriate safety guidelines to mitigate exposure risks.
