Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 307.99 g/mol gives 4-Hydroxy-3,3',4',5'-tetrachlorobiphenyl distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
4-Hydroxy-3,3',4',5'-tetrachlorobiphenyl (CAS 244035-65-2) is a high-purity analytical reference standard with the molecular formula C12H6Cl4O and a molecular weight of 307.99 g/mol.
4-Hydroxy-3,3',4',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. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
