Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 189.21 g/mol gives 5,8-dimethoxyquinoline distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
CATO supplies 5,8-dimethoxyquinoline (CAS 58868-41-0), a certified reference material (molecular formula C11H11NO2, MW 189.21 g/mol) for analytical method development and quality control.
5,8-dimethoxyquinoline (C11H11NO2) 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), 5,8-dimethoxyquinoline 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.
