Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 190.20 g/mol gives 6-Ethoxyquinoxalin-5-ol distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
CATO supplies 6-Ethoxyquinoxalin-5-ol (CAS 745048-89-9), a certified reference material (molecular formula C10H10N2O2, MW 190.20 g/mol) for analytical method development and quality control.
6-Ethoxyquinoxalin-5-ol (C10H10N2O2) contains an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage. It is notably hygroscopic, 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.
CATO manufactures 6-Ethoxyquinoxalin-5-ol under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
