The molecular framework of 3,4-Dihydroquinazolin-4-one 4(1H)-Quinazolinone 4(3H)-Quinazolinone 4(3H)-Quinazolone 4-Hydroxyquinazoline 4-Oxo-3,4-dihydroquinazoline 4-Oxoquinazoline 4-Quinazolinol 4-Quinazolinone 4-Quinazolone 491-36-1 Quinazolinone (C8H12N2O) is characterized by a nitrogen-containing heterocyclic scaffold, 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 aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

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.
