Chemical Structure

2-Hydroxy-2',3',4',5,5'-pentachlorobiphenyl CAS 67651-36-9 chemical structure

Description

Compared with other compounds in its class, the molecular weight of 342.43 g/mol gives 2-Hydroxy-2',3',4',5,5'-pentachlorobiphenyl distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

2-Hydroxy-2',3',4',5,5'-pentachlorobiphenyl (CAS 67651-36-9) is a high-purity analytical reference standard with the molecular formula C12H5Cl5O and a molecular weight of 342.43 g/mol.

2-Hydroxy-2',3',4',5,5'-pentachlorobiphenyl (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. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.

CATO manufactures 2-Hydroxy-2',3',4',5,5'-pentachlorobiphenyl 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.
