2-(5-((2,5-Dimethylbenzyl)thio)-4-ethyl-4H-1,2,4-triazol-3-yl)pyrazine CAS 586992-51-0

Description

As a certified reference material (CRM), 2-(5-((2,5-Dimethylbenzyl)thio)-4-ethyl-4H-1,2,4-triazol-3-yl)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.

2-(5-((2,5-Dimethylbenzyl)thio)-4-ethyl-4H-1,2,4-triazol-3-yl)pyrazine (CAS 586992-51-0) is a high-purity analytical reference standard with the molecular formula C17H19N5S and a molecular weight of 325.43 g/mol.

The molecular framework of 2-(5-((2,5-Dimethylbenzyl)thio)-4-ethyl-4H-1,2,4-triazol-3-yl)pyrazine (C17H19N5S) is characterized by a nitrogen-containing heterocyclic scaffold, a nitrile group, sulfur-containing functionality. 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.
