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.
3-(4-(3,4-Dimethoxybenzylidene)-2-methyl-5-oxo-4,5-dihydro-1H-imidazol-1-yl)-6-iodo-2-methylquinazolin-4(3H)-one (CAS 114496-25-2) is a high-purity analytical reference standard with the molecular formula C22H19IN4O4 and a molecular weight of 530.32 g/mol.
Structurally, 3-(4-(3,4-Dimethoxybenzylidene)-2-methyl-5-oxo-4,5-dihydro-1H-imidazol-1-yl)-6-iodo-2-methylquinazolin-4(3H)-one (C22H19IN4O4) contains a flavonoid core, an amide group, a hydroxyl group, an ether linkage, iodine substitution. The molecule exhibits a degree of unsaturation (DBE) of 15.0, corresponding to approximately 15 ring(s) or double-bond equivalent(s). With a molecular weight of 530.32 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.
