Description
As a certified reference material (CRM), 2-(4-Chlorophenyl)-3-[(4-methylphenyl)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.
2-(4-Chlorophenyl)-3-[(4-methylphenyl)sulfanyl]quinoline-4-carboxylic acid (CAS 477867-85-9) is a high-purity analytical reference standard with the molecular formula C23H16ClNO2S and a molecular weight of 405.90 g/mol.
2-(4-Chlorophenyl)-3-[(4-methylphenyl)sulfanyl]quinoline-4-carboxylic acid (C23H16ClNO2S) 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. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
