Chemical Structure

8-Bromo-1-(4-methoxybenzyl)-3-methyl-1H-imidazo[4,5-c]quinolin-2(3H)-one CAS 1802005-98-6 chemical structure

Description

The molecular framework of 8-Bromo-1-(4-methoxybenzyl)-3-methyl-1H-imidazo[4,5-c]quinolin-2(3H)-one (C19H16BrN3O2) is characterized by a steroid core, an amide group, a hydroxyl group, an ether linkage, bromine substitution. 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. 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).

8-Bromo-1-(4-methoxybenzyl)-3-methyl-1H-imidazo[4,5-c]quinolin-2(3H)-one (CAS 1802005-98-6), molecular formula C19H16BrN3O2 and molecular weight 398.25 g/mol, is a CATO reference standard with documented purity and traceability.

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.
