Toxicological and therapeutic implications of interactions between polychlorinated biphenyl sulfates and human transthyretin. has been approved by the Examining Committee for the thesis requirement for the Doctor of Philosophy degree in Human Toxicology at the May 2014 graduation. ii To my family iii ACKNOWLEDGEMENTS I would like to take this opportunity to(More)
The title compound, C(14)H(10)Cl(4)O(4)S, is a 2,2,2-trichloro-ethyl-protected precursor of 4'-chloro-biphenyl-3-yl sulfate, a sulfuric acid ester of 4'-chloro-biphenyl-3-ol. The C(aromatic)-O and O-S bond lengths of the C(aromatic)-O-S unit are comparable to those in structurally analogous biphenyl-4-yl 2,2,2-trichloro-ethyl sulfates with no(More)
The four independent mol-ecules in the asymmetric unit of the title compound, C(14)H(9)Cl(5)O(4)S, are related by pseudo-inversion centres. The mol-ecules have C(aromatic)-O bond lengths ranging from 1.426 (10) to 1.449 (9) Å and biphenyl-4-yl sulfate ester bond lengths ranging from 1.563 (6) to 1.586 (6) Å, which is comparable to structurally related(More)
The mol-ecular structure of the title compound, C(14)H(11)Cl(3)O(4)S, displays a biphenyl dihedral angle of 4.9 (2)° between the benzene rings, which is significantly smaller than the calculated dihedral angle of 41.2° of biphenyl derivatives without ortho substituents. The C(Ar)-O bond length of 1.432 (4) Å is comparable with other sulfuric acid(More)
BACKGROUND Polychlorinated biphenyls are persistent organic pollutants that can be metabolized via hydroxylated PCBs to PCB sulfate metabolites. The sensitive and selective analysis of PCB sulfate monoesters by gas chromatography-mass spectrometry (GC-MS) requires their derivatization, for example, as PCB 2,2,2-trichloroethyl (TCE) sulfate monoesters. To(More)
The title compound, C(14)H(10)Cl(4)O(4)S, is an inter-mediate in the synthesis of the PCB sulfate monoester of 4'-chloro-biphenyl-4-ol. Both the sulfate monoester and 4'-chloro-biphenyl-4-ol are metabolites of PCB 3 (4-chloro-biphen-yl). There are two mol-ecules with different conformations in the asymmetric unit. The solid state dihedral angles between the(More)
