8-Chloro-2-phenylquinazolin-4(3H)-one CAS 19407-55-7

Description

Compared with other compounds in its class, the molecular weight of 256.69 g/mol gives 8-Chloro-2-phenylquinazolin-4(3H)-one distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

CATO supplies 8-Chloro-2-phenylquinazolin-4(3H)-one (CAS 19407-55-7), a certified reference material (molecular formula C14H9ClN2O, MW 256.69 g/mol) for analytical method development and quality control.

Based on its molecular formula C14H9ClN2O, 8-Chloro-2-phenylquinazolin-4(3H)-one contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, chlorine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 256.69 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

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.
