Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
2-(2,4-Dioxo-1,4-dihydroquinazolin-3(2H)-yl)-N-(furan-2-ylmethyl)acetamide (CAS 688773-25-3) is a high-purity analytical reference standard with the molecular formula C15H13N3O4 and a molecular weight of 299.28 g/mol.
Structurally, 2-(2,4-Dioxo-1,4-dihydroquinazolin-3(2H)-yl)-N-(furan-2-ylmethyl)acetamide (C15H13N3O4) contains a flavonoid core, an amide group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 11.0, corresponding to approximately 11 ring(s) or double-bond equivalent(s). With a molecular weight of 299.28 g/mol, it falls into the medium-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).
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.
