N-(4-bromo-2,3-dimethylphenyl)-2-(4-formyl-2-methoxyphenoxy)acetamide (CAS 675855-76-2), molecular formula C18H18BrNO4 and molecular weight 392.24 g/mol, is a CATO reference standard with documented purity and traceability.
N-(4-bromo-2,3-dimethylphenyl)-2-(4-formyl-2-methoxyphenoxy)acetamide (C18H18BrNO4) 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. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
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.
