CAS 2051-24-3: 2,2′,3,3′,4,4′, 5,5′,6,6′-Decachlorobiphenyl

Description: 2,2′,3,3′,4,4′,5,5′,6,6′-Decachlorobiphenyl, with the CAS number 2051-24-3, is a synthetic organic compound belonging to the class of polychlorinated biphenyls (PCBs). This substance is characterized by its high degree of chlorination, featuring ten chlorine atoms attached to a biphenyl structure, which consists of two phenyl rings connected by a single bond. The extensive chlorination imparts significant hydrophobicity and lipophilicity, leading to its persistence in the environment and bioaccumulation in living organisms. Decachlorobiphenyl is typically a solid at room temperature and is insoluble in water, but soluble in organic solvents. Its chemical stability makes it resistant to degradation, contributing to environmental concerns associated with PCBs, including potential toxicity and carcinogenicity. Due to these properties, 2,2′,3,3′,4,4′,5,5′,6,6′-Decachlorobiphenyl has been subject to regulatory scrutiny and is banned or restricted in many countries. Its use has been largely phased out, but it may still be found in legacy products and contaminated sites.
