2,3,6,7-Tetramethylquinoxaline, 97% CAS 6957-19-3

Description

Compared with other compounds in its class, the molecular weight of 186.25 g/mol gives 2,3,6,7-Tetramethylquinoxaline, 97% distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

2,3,6,7-Tetramethylquinoxaline, 97% (CAS 6957-19-3) is a high-purity analytical reference standard with the molecular formula C12H14N2 and a molecular weight of 186.25 g/mol.

Owing to a nitrogen-containing heterocyclic scaffold, a nitrile group, 2,3,6,7-Tetramethylquinoxaline, 97% is typically off-white to pale yellow low-melting solid. Its solid-state physicochemical attributes — including a molecular weight of 186.25 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

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.
