4-Phenyl-5-(pyridin-3-yl)-1,2,4-4H-triazole-3-thiol CAS 57600-03-0

Description

4-Phenyl-5-(pyridin-3-yl)-1,2,4-4H-triazole-3-thiol (CAS 57600-03-0), molecular formula C13H10N4S and molecular weight 254.31 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of 4-Phenyl-5-(pyridin-3-yl)-1,2,4-4H-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.

CATO manufactures 4-Phenyl-5-(pyridin-3-yl)-1,2,4-4H-triazole-3-thiol under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
