Chemical Structure
Description
CATO supplies N-(4-Bromophenyl)-3-{[(4-nitrobenzyl)oxy]imino}propanamide (CAS 320417-76-3), a certified reference material (molecular formula C16H14BrN3O4, MW 392.20 g/mol) for analytical method development and quality control.
N-(4-Bromophenyl)-3-{[(4-nitrobenzyl)oxy]imino}propanamide (C16H14BrN3O4) contains a flavonoid core, an amide group, a hydroxyl group, an ether linkage, bromine substitution. It is notably hygroscopic, 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.
