4-(4-Bromobenzoyl)-3-hydroxy-5-(3-hydroxyphenyl)-1-((tetrahydrofuran-2-yl)methyl)-1H-pyrrol-2(5H)-one (CAS 617697-37-7) is a high-purity analytical reference standard with the molecular formula C22H20BrNO5 and a molecular weight of 458.30 g/mol.
4-(4-Bromobenzoyl)-3-hydroxy-5-(3-hydroxyphenyl)-1-((tetrahydrofuran-2-yl)methyl)-1H-pyrrol-2(5H)-one (C22H20BrNO5) 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. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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.
