Abstract
Methods are described for the synthesis of 4-chloro(1prime;,2prime;,3prime;,4prime;,5prime;,6′-13C6)biphenyl; 3,3′,4,4′-tetrachloro(13C12)biphenyl; and 2,2′,3,3′,5,5′,6,6′-octachloro(13C12)biphenyl; decachloro(13C12)biphenyl from (13C6)benzene of ≧ 99 atom % isotopic purity, on scales of 100 mg to 1 g. The gas chromatographic retention time of each 13C-polychlorinated biphenyl (PCB) matched that of the corresponding unlabeled commercial reference standard, and the mass spectrum of each compound was consistent with an isotopic purity of ≧ 99 atom % 13C. These compounds are useful as recovery surrogates and internal standards in the determination of PCBs in a variety of complex matrices.
