Description
Ethyl 3-benzoyl-1-(2,4-dichlorobenzyl)-2-methyl-7-oxo-4,7-dihydro-1H-pyrrolo[3,2-b]pyridine-6-carboxylate (CAS 339028-67-0) is a high-purity analytical reference standard with the molecular formula C25H20Cl2N2O4 and a molecular weight of 483.34 g/mol.
Structurally, Ethyl 3-benzoyl-1-(2,4-dichlorobenzyl)-2-methyl-7-oxo-4,7-dihydro-1H-pyrrolo[3,2-b]pyridine-6-carboxylate (C25H20Cl2N2O4) contains a flavonoid core, an amide group, a hydroxyl group, an ether linkage, chlorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 16.0, corresponding to approximately 16 ring(s) or double-bond equivalent(s). With a molecular weight of 483.34 g/mol, it falls into the moderately-high-molecular-weight range. 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.
