:2,2',3,3',4,5',6,6'-octachlorobiphenyl
Description:
2,2',3,3',4,5',6,6'-octachlorobiphenyl, identified by its CAS number 40186-71-8, is a synthetic organic compound belonging to the class of polychlorinated biphenyls (PCBs). This compound consists of two biphenyl rings with eight chlorine atoms substituted at various positions, which significantly alters its physical and chemical properties. It is characterized by its high stability, low volatility, and resistance to degradation, making it persistent in the environment. Due to its hydrophobic nature, it tends to bioaccumulate in the fatty tissues of living organisms, leading to potential toxic effects. The compound is typically colorless to pale yellow and has a high melting point. Its use has been largely restricted or banned in many countries due to environmental and health concerns, particularly its potential as an endocrine disruptor and its association with various adverse health effects in humans and wildlife. Proper handling and disposal are crucial to mitigate its environmental impact.

CAS:Controlled Product<p>2,2',3,3',4,5',6,6'-Octachlorobiphenyl (OCB) is a polychlorinated biphenyl that has been used as an extraction solvent for fats and oils. OCB is a mixture of octachloro-substituted biphenyls with varying degrees of chlorination. The different chlorination levels are correlated to the solubility of the individual compounds. In particular, 4- and 6-chlorinated biphenyls have been found to be more soluble than 3- or 5-chlorinated biphenyls. Spectroscopic methods can be used to determine the abundances of each type of compound in the mixture. Further spectrometric analysis can be used to identify which compounds are present at what concentrations. Hexane is often used as a solvent during this process because it dissolves all four types of compounds equally well. Mass spectrometric analysis can then be used to measure the concentration</p>Formula:C12H2Cl8Purity:Min. 95%Molecular weight:429.8 g/mol
