2-Bromo-1-(4-fluorophenoxy)-4-nitrobenzene (CAS 477856-83-0), molecular formula C12H7BrFNO3 and molecular weight 312.09 g/mol, is a CATO reference standard with documented purity and traceability.
2-Bromo-1-(4-fluorophenoxy)-4-nitrobenzene (C12H7BrFNO3) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, fluorine/bromine substitution. It is notably hygroscopic, halogen substitution raises its density and boiling point, its high carbon-to-hydrogen ratio confers good lipid solubility, 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.
