Chemical Structure
Description
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.
CATO supplies 5-(4-Chlorophenyl)-3-hydroxy-4-(4-methoxybenzoyl)-1-((tetrahydrofuran-2-yl)methyl)-1H-pyrrol-2(5H)-one (CAS 496798-24-4), a certified reference material (molecular formula C23H22ClNO5, MW 427.88 g/mol) for analytical method development and quality control.
5-(4-Chlorophenyl)-3-hydroxy-4-(4-methoxybenzoyl)-1-((tetrahydrofuran-2-yl)methyl)-1H-pyrrol-2(5H)-one (C23H22ClNO5) contains a flavonoid core, an amide group, a hydroxyl group, an ether linkage, chlorine 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).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
