CAS 37680-65-2: 2,2′,5′-Trichlorobiphenyl
Description:2,2′,5′-Trichlorobiphenyl, with the CAS number 37680-65-2, 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, 2', and 5' positions. This compound is typically a colorless to pale yellow solid at room temperature and is insoluble in water but soluble in organic solvents. 2,2′,5′-Trichlorobiphenyl exhibits 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 electrical equipment and as a heat transfer medium. However, due to its toxicological profile and potential environmental impact, including bioaccumulation and endocrine disruption, its production and use have been heavily regulated or banned in many countries. Safety measures are essential when handling this compound to mitigate exposure risks.
