1,2-Dimethyl-6-(thiophen-2-yl)-1H-imidazo[4,5-g]quinoxaline CAS 226717-28-8

Description

The occurrence of 1,2-Dimethyl-6-(thiophen-2-yl)-1H-imidazo[4,5-g]quinoxaline is closely related to a nitrogen-containing heterocyclic scaffold, a nitrile group, sulfur-containing functionality in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

1,2-Dimethyl-6-(thiophen-2-yl)-1H-imidazo[4,5-g]quinoxaline (CAS 226717-28-8) is a high-purity analytical reference standard with the molecular formula C15H12N4S and a molecular weight of 280.35 g/mol.

Owing to a nitrogen-containing heterocyclic scaffold, a nitrile group, sulfur-containing functionality, 1,2-Dimethyl-6-(thiophen-2-yl)-1H-imidazo[4,5-g]quinoxaline is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 280.35 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

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.
