2,3',5-trichlorobiphenyl

Description:

2,3',5-Trichlorobiphenyl is a chlorinated biphenyl compound, part of a larger class of chemicals known as polychlorinated biphenyls (PCBs). It features two phenyl rings connected by a single bond, with three chlorine atoms substituted at the 2, 3', and 5 positions on the biphenyl structure. This compound is typically a white to light yellow solid at room temperature and is known for its hydrophobic nature, making it poorly soluble in water but soluble in organic solvents. 2,3',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 capacitors and transformers. However, due to its toxicological profile, including potential carcinogenicity and endocrine-disrupting effects, its production and use have been heavily regulated or banned in many countries. Environmental monitoring is essential to assess its presence and impact, as it can accumulate in the food chain and pose risks to human health and ecosystems.

2,3',5-Trichlorobiphenyl is a chlorinated aromatic compound that is considered to be a pre-existing contaminant. It is the most abundant polychlorinated biphenyl (PCB) in the environment and has been detected in all living organisms. 2,3',5-Trichlorobiphenyl (TCBP) is bioconverted into dichlorobenzene under anaerobic conditions and then dechlorinated by reductive dehalogenase enzymes to 2,3,4,6-tetrachlorophenol (2,3',4,6'-TCP). TCBP can also be degraded by bacteria to form hydrogen gas and other pre-existing compounds. The metabolism of TCBP occurs mainly in the liver and intestine of animals.
2,3',5-Trichlorobiphenyl can also form congeners with other PCBs through coplanar interactions. These congeners have been shown to
