(Z)-3-(((6-Oxocyclohexa-2,4-dien-1-ylidene)methyl)amino)-2-phenylquinazolin-4(3H)-one CAS 73861-06-0

Description

Compared with other compounds in its class, the molecular weight of 341.36 g/mol gives (Z)-3-(((6-Oxocyclohexa-2,4-dien-1-ylidene)methyl)amino)-2-phenylquinazolin-4(3H)-one distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

CATO supplies (Z)-3-(((6-Oxocyclohexa-2,4-dien-1-ylidene)methyl)amino)-2-phenylquinazolin-4(3H)-one (CAS 73861-06-0), a certified reference material (molecular formula C21H15N3O2, MW 341.36 g/mol) for analytical method development and quality control.

The molecular framework of (Z)-3-(((6-Oxocyclohexa-2,4-dien-1-ylidene)methyl)amino)-2-phenylquinazolin-4(3H)-one (C21H15N3O2) 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 the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.

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.
