Chemical Structure
Description
Ethyl 4-((furan-2-ylmethyl)amino)-6-oxo-1-phenyl-1,6-dihydropyridazine-3-carboxylate (C18H17N3O4) contains a flavonoid core, an amide group, a hydroxyl group, an ether linkage. It is notably hygroscopic, 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).
Ethyl 4-((furan-2-ylmethyl)amino)-6-oxo-1-phenyl-1,6-dihydropyridazine-3-carboxylate (CAS 921899-71-0) is a high-purity analytical reference standard with the molecular formula C18H17N3O4 and a molecular weight of 339.35 g/mol.
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.
