Chemical Structure
Description
The molecular framework of 6-phenyl-1,2,3,4,5,6,7,8-octahydroquinazoline-2,4-dione (C14H14N2O2) 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 its high hydrophobicity (logP), 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).
6-phenyl-1,2,3,4,5,6,7,8-octahydroquinazoline-2,4-dione (CAS 1495390-92-5) is a high-purity analytical reference standard with the molecular formula C14H14N2O2 and a molecular weight of 242.27 g/mol.
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.
