Chemical Structure
Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 1-[4-(Benzyloxy)-3-fluorophenoxy]-2-bromo-4-nitrobenzene.
1-[4-(Benzyloxy)-3-fluorophenoxy]-2-bromo-4-nitrobenzene (CAS 478039-83-7) is a high-purity analytical reference standard with the molecular formula C19H13BrFNO4 and a molecular weight of 418.21 g/mol.
1-[4-(Benzyloxy)-3-fluorophenoxy]-2-bromo-4-nitrobenzene (C19H13BrFNO4) contains a flavonoid core, an amide group, a hydroxyl group, an ether linkage, fluorine/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. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
