2,2',3,4',5,6,6'-heptachlorobiphenyl

Description:
2,2',3,4',5,6,6'-heptachlorobiphenyl, with the CAS number 74487-85-7, is a member of the polychlorinated biphenyl (PCB) family, which consists of biphenyl molecules with multiple chlorine atoms substituted at various positions. This compound is characterized by its high degree of chlorination, which contributes to its chemical stability and lipophilicity, making it persistent in the environment. It is typically a colorless to light yellow solid and is insoluble in water but soluble in organic solvents. Due to its hydrophobic nature, it tends to bioaccumulate in the fatty tissues of living organisms, leading to potential ecological and health risks. 2,2',3,4',5,6,6'-heptachlorobiphenyl has been associated with various adverse effects, including endocrine disruption and potential carcinogenicity. Its production and use have been largely banned or restricted in many countries due to environmental and health concerns, and it is monitored as a persistent organic pollutant (POP) under international agreements.
