CAS 7012-37-5: 2,4,4′-Trichlorobiphenyl
Description:2,4,4′-Trichlorobiphenyl, with the CAS number 7012-37-5, is a chlorinated biphenyl compound that belongs to the class of polychlorinated biphenyls (PCBs). It is characterized by the presence of three chlorine atoms attached to a biphenyl structure, specifically at the 2, 4, and 4' positions. This compound is typically a colorless to light yellow solid at room temperature and is insoluble in water but soluble in organic solvents. 2,4,4′-Trichlorobiphenyl exhibits high thermal stability and resistance to degradation, which contributes to its persistence in the environment. It has been used in various industrial applications, including as a dielectric fluid in capacitors and transformers. However, due to its toxicological profile, including potential carcinogenic effects and environmental persistence, its production and use have been heavily regulated or banned in many countries. The compound can bioaccumulate in living organisms, leading to concerns regarding its impact on human health and ecosystems.
