Chemical Structure

2-Methyl-3-(methylthio)pyrazine CAS 2882-20-4 chemical structure

Description

CATO supplies 2-Methyl-3-(methylthio)pyrazine (CAS 2882-20-4), a certified reference material (molecular formula C6H8N2S, MW 140.21 g/mol) for analytical method development and quality control.

The molecular framework of 2-Methyl-3-(methylthio)pyrazine (C6H8N2S) is characterized by a nitrile group, sulfur-containing functionality, 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. 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.

As a certified reference material (CRM), 2-Methyl-3-(methylthio)pyrazine meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
