4,4''-Dichloro-[1,1':3',1''-terphenyl]-5'-ol CAS 115752-49-3

Description

CATO manufactures 4,4''-Dichloro-[1,1':3',1''-terphenyl]-5'-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.

4,4''-Dichloro-[1,1':3',1''-terphenyl]-5'-ol (CAS 115752-49-3), molecular formula C18H12Cl2O and molecular weight 315.19 g/mol, is a CATO reference standard with documented purity and traceability.

4,4''-Dichloro-[1,1':3',1''-terphenyl]-5'-ol (C18H12Cl2O) contains a steroid core, a hydroxyl group, an ether linkage, chlorine substitution. 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.

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.
