Description

Compared with other compounds in its class, the molecular weight of 139.16 g/mol gives 3-Methoxy-5-methylpyrazin-2-amine distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

3-Methoxy-5-methylpyrazin-2-amine (CAS 89464-87-9) is a high-purity analytical reference standard with the molecular formula C6H9N3O and a molecular weight of 139.16 g/mol.

The molecular framework of 3-Methoxy-5-methylpyrazin-2-amine (C6H9N3O) is characterized by an amide group, a hydroxyl group, an ether linkage, an aromatic ring system. 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.
