General description
Polychlorinated biphenyls (PCBs) belong to the class of highly toxic pollutants commonly found in various environmental matrices and food products. They find a variety of applications as flame retardants, plasticizers, dielectric and heat transfer fluids, etc.
Application
PCB No 3 may be used as an analytical reference standard for the quantification of the analyte in aqueous solution in the presence of dissolved organic carbon using high-performance liquid chromatography technique.
Refer to the product′s Certificate of Analysis for more information on a suitable instrument technique. Contact Technical Service for further support.

Despite increasing evidence for a major role for sulfation in the metabolism of lower-chlorinated polychlorinated biphenyls in vitro and in vivo, and initial evidence for potential bioactivities of the resulting sulfate ester metabolites, the formation of PCB sulfates in PCB

Model dioxin compounds 4-chlorobiphenyl (4CB), octa-chlorodibenzo-p-dioxin (OCDD), and octachlorodibenzofuran (OCDF) were degraded by a mechanochemical (MC) process that involved milling with calcium oxide by use of a planetary ball mill. The degradation of 4CB produced mainly chloride ions and biphenyl

The present study was undertaken to investigate the endocrine disrupting activity of PCB3 and its hydroxylated metabolites 4-OH-PCB3 and 3,4-diOH-PCB3 in ovarian follicle cells derived from prepubertal animals with special emphasis on cytochrome P-450-dependent aromatase (CYP19). Aromatase activity was assayed
