ethyl 4-([(4-bromo-2-formylphenoxy)acetyl]amino)benzoate (CAS 832674-72-3), molecular formula C18H16BrNO5 and molecular weight 406.23 g/mol, is a CATO reference standard with documented purity and traceability.
ethyl 4-([(4-bromo-2-formylphenoxy)acetyl]amino)benzoate (C18H16BrNO5) 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. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
