6-Chloro-2-(4-chlorophenyl)-3-[(4-chlorophenyl)sulfanyl]quinoline-4-carboxylic acid (CAS 477886-51-4), molecular formula C22H12Cl3NO2S and molecular weight 460.76 g/mol, is a CATO reference standard with documented purity and traceability.
6-Chloro-2-(4-chlorophenyl)-3-[(4-chlorophenyl)sulfanyl]quinoline-4-carboxylic acid (C22H12Cl3NO2S) contains a steroid core, an amide group, a sulfone group, 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, the carboxyl group imparts weak acidity; 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.
As a certified reference material (CRM), 6-Chloro-2-(4-chlorophenyl)-3-[(4-chlorophenyl)sulfanyl]quinoline-4-carboxylic acid 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.
