Chemical Structure
Description
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.
6-Bromo-3-(4-methylbenzyl)quinazolin-4(3H)-one (CAS 302913-32-2) is a high-purity analytical reference standard with the molecular formula C16H13BrN2O and a molecular weight of 329.19 g/mol.
The molecular framework of 6-Bromo-3-(4-methylbenzyl)quinazolin-4(3H)-one (C16H13BrN2O) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, bromine substitution. 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 aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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.
