Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
CATO supplies 4-Hydroxy-2',3,5,5'-tetrachlorobiphenyl (CAS 245084-57-5), a certified reference material (molecular formula C12H6Cl4O, MW 307.99 g/mol) for analytical method development and quality control.
4-Hydroxy-2',3,5,5'-tetrachlorobiphenyl (C12H6Cl4O) 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.
As a certified reference material (CRM), 4-Hydroxy-2',3,5,5'-tetrachlorobiphenyl meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
