Chemical Structure

2,6-Dimethylpyrazine CAS 108-50-9 chemical structure

Description

The occurrence of 2,6-Dimethylpyrazine is closely related to a nitrile group, an aromatic ring system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

2,6-Dimethylpyrazine (CAS 108-50-9) is a high-purity analytical reference standard with the molecular formula C6H8N2 and a molecular weight of 108.14 g/mol.

Owing to a nitrile group, an aromatic ring system, 2,6-Dimethylpyrazine is typically off-white to pale yellow liquid. Its solid-state physicochemical attributes — including a molecular weight of 108.14 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.
