2,3,5-Trimethylpyrazine CAS 14667-55-1 chemical structure

Description

Compared with other compounds in its class, the molecular weight of 122.17 g/mol gives 2,3,5-Trimethylpyrazine distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

2,3,5-Trimethylpyrazine (CAS 14667-55-1) is a high-purity analytical reference standard with the molecular formula C7H10N2 and a molecular weight of 122.17 g/mol.

2,3,5-Trimethylpyrazine (C7H10N2) contains a nitrile group, an aromatic ring system. Its physicochemical properties are representative of its class; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.

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.
