Chemical Structure
Description
3-((3-Chlorophenyl)sulfonyl)-6,7-difluoro-1-(4-methylbenzyl)quinolin-4(1H)-one (C23H16ClF2NO3S) contains a steroid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage, fluorine/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 high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
3-((3-Chlorophenyl)sulfonyl)-6,7-difluoro-1-(4-methylbenzyl)quinolin-4(1H)-one (CAS 1326901-66-9), molecular formula C23H16ClF2NO3S and molecular weight 459.89 g/mol, is a CATO reference standard with documented purity and traceability.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
As a certified reference material (CRM), 3-((3-Chlorophenyl)sulfonyl)-6,7-difluoro-1-(4-methylbenzyl)quinolin-4(1H)-one 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.
