Chemical Structure
Description
N-[(3,4-Dichlorophenyl)methoxy]-2,5-bis(2,2,2-trifluoroethoxy)benzamide (CAS 320418-35-7) is a high-purity analytical reference standard with the molecular formula C18H13Cl2F6NO4 and a molecular weight of 492.20 g/mol.
N-[(3,4-Dichlorophenyl)methoxy]-2,5-bis(2,2,2-trifluoroethoxy)benzamide (C18H13Cl2F6NO4) contains a flavonoid core, an amide group, a hydroxyl group, an ether linkage, fluorine/chlorine 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.
