2-Ethyl-3,5-dimethylpyrazine(Mixture of isomers) CAS 13925-07-0

Description

Based on its molecular formula C8H12N2, 2-Ethyl-3,5-dimethylpyrazine(Mixture of isomers) contains a nitrogen-containing heterocyclic scaffold, a nitrile group; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 136.19 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).

2-Ethyl-3,5-dimethylpyrazine(Mixture of isomers) (CAS 13925-07-0) is a high-purity analytical reference standard with the molecular formula C8H12N2 and a molecular weight of 136.19 g/mol.

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.
