2,3-Dimethyl-6-(4-methylpiperazin-1-yl)quinoxaline CAS 383148-06-9

Description

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.

2,3-Dimethyl-6-(4-methylpiperazin-1-yl)quinoxaline (CAS 383148-06-9) is a high-purity analytical reference standard with the molecular formula C15H20N4 and a molecular weight of 256.35 g/mol.

Based on its molecular formula C15H20N4, 2,3-Dimethyl-6-(4-methylpiperazin-1-yl)quinoxaline contains a nitrogen-containing heterocyclic scaffold, a nitrile group; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 256.35 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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).

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.
