PCB 136, 2,2′,3,3′,6,6′-hexachlorobiphenyl-4-ol (4-136), 2,2′,3,3′,6,6′-hexachlorobiphenyl-5-ol (5-136), 4,5-dimethoxy-2,2′,3,3′,6,6′-hexachlorobiphenyl (methylated derivative of 2,2′,3,3′,6,6′-hexachlorobiphenyl-4,5-diol; 4,5-136) and 2,2′,3′,4,6,6′-hexachloro-3-methoxybiphenyl (methylated derivative of 2,2′,3′,4,6,6′-hexachlorobiphenyl-3-ol; 3-150) were synthesized as described previously (Waller et al. 1999 (link)). The chemical structures and the abbreviations of the HO-PCB metabolites are shown in Figure 1A . Surrogate recovery standards (2,3,4′,5,6-pentachlorobiphenyl, PCB 117; 2′,3,3′,4,5,5′-hexachlorobiphenyl-4-ol, 4-159) and internal standard (2,2′,3,4,4′,5,6,6′-octachlorobiphenyl, PCB 204) were purchased from Accustandard (New Haven, CT). NAC and tetrabutylammonium sulfite were purchased from Fisher Scientific (Pittsburg, PA, USA). L-Glutathione and β-nicotinamide adenine dinucleotide 2′-phosphate reduced tetrasodium salt hydrate (NADPH) were obtained from Sigma-Aldrich (St. Louis, MO, USA). Pesticide grade n-hexane, 2-propanol and methyl tert-butyl ether (MTBE) were purchased from Fisher Scientific (Pittsburg, PA, USA).

About PubCompare
Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.
We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.
However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
