Description
Compared with other compounds in its class, the molecular weight of 317.31 g/mol gives N-(2-Fluoro-4-methoxyphenyl)-4-oxo-5,6,7,8-tetrahydro-4H-cyclohepta[b]furan-3-carboxamide distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
CATO supplies N-(2-Fluoro-4-methoxyphenyl)-4-oxo-5,6,7,8-tetrahydro-4H-cyclohepta[b]furan-3-carboxamide (CAS 225240-81-3), a certified reference material (molecular formula C17H16FNO4, MW 317.31 g/mol) for analytical method development and quality control.
N-(2-Fluoro-4-methoxyphenyl)-4-oxo-5,6,7,8-tetrahydro-4H-cyclohepta[b]furan-3-carboxamide (C17H16FNO4) contains a flavonoid core, an amide group, a hydroxyl group, an ether linkage, fluorine substitution. Halogen substitution raises its density and boiling point, 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.
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.
