Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
Dimethyl 4-(5-(3,4-dichlorophenyl)furan-2-yl)-2,6-dimethyl-1,4-dihydropyridine-3,5-dicarboxylate (CAS 372495-88-0) is a high-purity analytical reference standard with the molecular formula C21H19Cl2NO5 and a molecular weight of 436.29 g/mol.
Dimethyl 4-(5-(3,4-dichlorophenyl)furan-2-yl)-2,6-dimethyl-1,4-dihydropyridine-3,5-dicarboxylate (C21H19Cl2NO5) 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 presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
