Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 2-[(4-oxo-3,4-dihydroquinazolin-2-yl)methyl]benzoic acid.

2-[(4-oxo-3,4-dihydroquinazolin-2-yl)methyl]benzoic acid (CAS 540495-74-7) is a high-purity analytical reference standard with the molecular formula C16H12N2O3 and a molecular weight of 280.28 g/mol.

Structurally, 2-[(4-oxo-3,4-dihydroquinazolin-2-yl)methyl]benzoic acid (C16H12N2O3) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 12.0, corresponding to approximately 12 ring(s) or double-bond equivalent(s). With a molecular weight of 280.28 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).

This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
