Description
As a certified reference material (CRM), 3-(4-Methylphenyl)-2-oxo-1,2-dihydroquinoline-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.
3-(4-Methylphenyl)-2-oxo-1,2-dihydroquinoline-4-carboxylic acid (CAS 400082-48-6), molecular formula C17H13NO3 and molecular weight 279.29 g/mol, is a CATO reference standard with documented purity and traceability.
3-(4-Methylphenyl)-2-oxo-1,2-dihydroquinoline-4-carboxylic acid (C17H13NO3) contains a steroid core, an amide group, a hydroxyl group, an ether linkage. 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.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
