Chemical Structure
Description
3-(((3-Methoxyphenyl)amino)methylene)-1,5-dioxaspiro[5.5]undecane-2,4-dione (C17H19NO5) contains a flavonoid core, an amide group, a hydroxyl group, an ether linkage. 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).
3-(((3-Methoxyphenyl)amino)methylene)-1,5-dioxaspiro[5.5]undecane-2,4-dione (CAS 369394-57-0) is a high-purity analytical reference standard with the molecular formula C17H19NO5 and a molecular weight of 317.34 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.
