Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
CATO supplies 1-Ethyl-3-methyl-2-oxo-N-(spiro[benzo[d][1,3]dioxole-2,1'-cyclopentan]-5-yl)-1,2-dihydroquinoxaline-6-carboxamide (CAS 924228-31-9), a certified reference material (molecular formula C23H23N3O4, MW 405.45 g/mol) for analytical method development and quality control.
Based on its molecular formula C23H23N3O4, 1-Ethyl-3-methyl-2-oxo-N-(spiro[benzo[d][1,3]dioxole-2,1'-cyclopentan]-5-yl)-1,2-dihydroquinoxaline-6-carboxamide contains a flavonoid core, an amide group, a hydroxyl group, an ether linkage; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 405.45 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
