3,3,7-Trimethyl-3,4-dihydroquinoxalin-2(1H)-one CAS 147245-26-9

Description

Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, 3,3,7-Trimethyl-3,4-dihydroquinoxalin-2(1H)-one is typically off-white to pale yellow low-melting solid. Its solid-state physicochemical attributes — including a molecular weight of 190.24 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).

3,3,7-Trimethyl-3,4-dihydroquinoxalin-2(1H)-one (CAS 147245-26-9) is a high-purity analytical reference standard with the molecular formula C11H14N2O and a molecular weight of 190.24 g/mol.

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.
