CAS 2050-68-2: 4,4′-Dichlorobiphenyl

Description: 4,4′-Dichlorobiphenyl, with the CAS number 2050-68-2, is a chlorinated biphenyl compound characterized by the presence of two chlorine atoms positioned at the para positions of the biphenyl structure. This compound is part of a larger group known as polychlorinated biphenyls (PCBs), which are synthetic organic chemicals. It is typically a colorless to pale yellow solid with low solubility in water but higher solubility in organic solvents. 4,4′-Dichlorobiphenyl is known for its 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, although its production and use have been heavily regulated or banned in many countries due to environmental and health concerns, including its potential as an endocrine disruptor and its classification as a probable human carcinogen. Proper handling and disposal are essential to mitigate its environmental impact.
