Chemical Structure
Description
7-Methoxy-3,4-dihydroquinolin-2(1H)-one (CAS 22246-17-9), molecular formula C10H11NO2 and molecular weight 177.20 g/mol, is a CATO reference standard with documented purity and traceability.
7-Methoxy-3,4-dihydroquinolin-2(1H)-one (C10H11NO2) contains an amino-acid-derived structure, 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 aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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), 7-Methoxy-3,4-dihydroquinolin-2(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.
