2,3-DICHLOROBIPHENYL

Description:
2,3-Dichlorobiphenyl, with the CAS number 16605-91-7, is a chlorinated biphenyl compound characterized by the presence of two chlorine atoms attached to a biphenyl structure. This compound typically appears as a colorless to pale yellow solid and is insoluble in water but soluble in organic solvents. It is part of a larger group of polychlorinated biphenyls (PCBs), which are known for their chemical stability and resistance to degradation. 2,3-Dichlorobiphenyl exhibits moderate toxicity and potential environmental persistence, raising concerns regarding its impact on human health and ecosystems. It can bioaccumulate in living organisms, leading to long-term ecological effects. The compound is primarily used in industrial applications, including as a dielectric fluid in capacitors and transformers, although its use has been heavily regulated or banned in many countries due to environmental and health risks. Proper handling and disposal are essential to mitigate its potential hazards.
