Description

Compared with other compounds in its class, the molecular weight of 158.24 g/mol gives 5-Methylpyrazine-2,3(1H,4H)-dithione distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

5-Methylpyrazine-2,3(1H,4H)-dithione (CAS 87256-74-4) is a high-purity analytical reference standard with the molecular formula C5H6N2S2 and a molecular weight of 158.24 g/mol.

The molecular framework of 5-Methylpyrazine-2,3(1H,4H)-dithione (C5H6N2S2) is characterized by a nitrile group, sulfur-containing functionality. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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).

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.
