2,2′,6,6′-Tetrachlorobiphenyl, with the CAS number 15968-05-5, is a chlorinated biphenyl compound that belongs to the class of polychlorinated biphenyls (PCBs). It is characterized by the presence of four chlorine atoms attached to a biphenyl structure, specifically at the 2, 2', 6, and 6' positions. This compound is typically a colorless to light yellow solid at room temperature and is insoluble in water but soluble in organic solvents. Due to its chemical stability and hydrophobic nature, 2,2′,6,6′-Tetrachlorobiphenyl has been used in various industrial applications, including as a dielectric fluid in capacitors and transformers. However, like other PCBs, it is recognized for its environmental persistence and potential toxicity, leading to bioaccumulation in the food chain and adverse health effects in humans and wildlife. Regulatory measures have been implemented in many countries to limit its use and manage its environmental impact.
