Chemical Structure

3,4-dihydro-1H-quinoxalin-2-one CAS 59564-59-9 chemical structure

Description

3,4-dihydro-1H-quinoxalin-2-one (C8H8N2O) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage. Its physicochemical properties are representative of its class; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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).

CATO supplies 3,4-dihydro-1H-quinoxalin-2-one (CAS 59564-59-9), a certified reference material (molecular formula C8H8N2O, MW 148.16 g/mol) for analytical method development and quality control.

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.
