Chemical Structure

2-Ethylpyrazine CAS 13925-00-3 chemical structure

Description

Structurally, 2-Ethylpyrazine (C6H8N2) contains a nitrile group, an aromatic ring system. The molecule exhibits a degree of unsaturation (DBE) of 4.0, corresponding to approximately 4 ring(s) or double-bond equivalent(s). With a molecular weight of 108.14 g/mol, it falls into the low-molecular-weight range. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.

2-Ethylpyrazine (CAS 13925-00-3), molecular formula C6H8N2 and molecular weight 108.14 g/mol, is a CATO reference standard with documented purity and traceability.

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.
