General description
3-Chlorobiphenyl is a chlorinated biphenyl compound, which can be prepared, via phase transfer Gomberg-Bachmann-Hey reaction. It involves the condensation of 3-chlorobenzenediazonium tetrafluoroborate with 18-crown-6 in the presence of potassium acetate.
Polychlorinated biphenyls (PCBs) are a class of highly toxic pollutants 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 1 may be used as an analytical reference standard for the quantification of the analyte in natural matrices using an on-line system for subcritical water extraction combined with high-performance liquid chromatography (HPLC).
