Description

Compared with other compounds in its class, the molecular weight of 329.40 g/mol gives 3-(Methylamino)-1,2-diphenyl-2,3-dihydroquinazolin-4(1H)-one distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

CATO supplies 3-(Methylamino)-1,2-diphenyl-2,3-dihydroquinazolin-4(1H)-one (CAS 61573-11-3), a certified reference material (molecular formula C21H19N3O, MW 329.40 g/mol) for analytical method development and quality control.

The molecular framework of 3-(Methylamino)-1,2-diphenyl-2,3-dihydroquinazolin-4(1H)-one (C21H19N3O) is characterized by a steroid core, 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).

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.

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.
