5-Phenyl-3-(prop-2-yn-1-ylthio)-1H-1,2,4-triazole CAS 66894-07-3 chemical structure

Description

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.

5-Phenyl-3-(prop-2-yn-1-ylthio)-1H-1,2,4-triazole (CAS 66894-07-3) is a high-purity analytical reference standard with the molecular formula C11H9N3S and a molecular weight of 215.27 g/mol.

The molecular framework of 5-Phenyl-3-(prop-2-yn-1-ylthio)-1H-1,2,4-triazole (C11H9N3S) 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).

CATO manufactures 5-Phenyl-3-(prop-2-yn-1-ylthio)-1H-1,2,4-triazole 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.
