Chemical Structure
Description
N-(3-Methoxypropyl)-2,4-dioxo-3-pentyl-1,2,3,4-tetrahydroquinazoline-7-carboxamide (CAS 892264-06-1), molecular formula C18H25N3O4 and molecular weight 347.41 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of N-(3-Methoxypropyl)-2,4-dioxo-3-pentyl-1,2,3,4-tetrahydroquinazoline-7-carboxamide (C18H25N3O4) is characterized by a flavonoid core, an amide group, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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.
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.
