Chemical Structure
Description
As a certified reference material (CRM), 4-Phenyl-5-pyridin-4-yl-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.
CATO supplies 4-Phenyl-5-pyridin-4-yl-4H-[1,2,4]triazole-3-thiol (CAS 16629-40-6), a certified reference material (molecular formula C13H10N4S, MW 254.31 g/mol) for analytical method development and quality control.
The molecular framework of 4-Phenyl-5-pyridin-4-yl-4H-[1,2,4]triazole-3-thiol (C13H10N4S) is characterized by a nitrogen-containing heterocyclic scaffold, a nitrile group, sulfur-containing functionality. 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. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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.
