Chemical Structure

2,3-Dimethylquinoxaline CAS 2379-55-7 chemical structure

Description

Based on its molecular formula C10H10N2, 2,3-Dimethylquinoxaline contains a nitrogen-containing heterocyclic scaffold, a nitrile group; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 158.20 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

2,3-Dimethylquinoxaline (CAS 2379-55-7) is a high-purity analytical reference standard with the molecular formula C10H10N2 and a molecular weight of 158.20 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.

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.
