5,8-Dimethoxy-4-methyl-6-nitroquinolin-2(1H)-one CAS 66570-46-5

Description

Owing to an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage, 5,8-Dimethoxy-4-methyl-6-nitroquinolin-2(1H)-one is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 264.23 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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).

5,8-Dimethoxy-4-methyl-6-nitroquinolin-2(1H)-one (CAS 66570-46-5), molecular formula C12H12N2O5 and molecular weight 264.23 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.
