2-(2-Bromo-6-ethoxy-4-formylphenoxy)-N-(naphthalen-1-yl)acetamide (CAS 832674-12-1), molecular formula C21H18BrNO4 and molecular weight 428.28 g/mol, is a CATO reference standard with documented purity and traceability.
2-(2-Bromo-6-ethoxy-4-formylphenoxy)-N-(naphthalen-1-yl)acetamide (C21H18BrNO4) contains a flavonoid core, an amide group, a hydroxyl group, an ether linkage, bromine 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.
