Chemical Structure
Description
3,3',4',5,5'-Pentachloro-[1,1'-biphenyl]-4-ol (CAS 130689-92-8) is a high-purity analytical reference standard with the molecular formula C12H5Cl5O and a molecular weight of 342.43 g/mol.
3,3',4',5,5'-Pentachloro-[1,1'-biphenyl]-4-ol (C12H5Cl5O) contains a hydroxyl group, an ether linkage, chlorine substitution, an aromatic ring system. Halogen substitution raises its density and boiling point, its high carbon-to-hydrogen ratio confers good lipid solubility; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
CATO manufactures 3,3',4',5,5'-Pentachloro-[1,1'-biphenyl]-4-ol under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
