Chemical Structure
Description
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.
5-(4-Ethoxyphenyl)-4-methyl-4H-1,2,4-triazole-3-thiol (CAS 334497-06-2) is a high-purity analytical reference standard with the molecular formula C11H13N3OS and a molecular weight of 235.31 g/mol.
The molecular framework of 5-(4-Ethoxyphenyl)-4-methyl-4H-1,2,4-triazole-3-thiol (C11H13N3OS) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), 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.
As a certified reference material (CRM), 5-(4-Ethoxyphenyl)-4-methyl-4H-1,2,4-triazole-3-thiol 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.
