2-((4-Ethyl-5-(p-tolyl)-4h-1,2,4-triazol-3-yl)thio)acetohydrazide CAS 893726-73-3 chemical structure

Description

The occurrence of 2-((4-Ethyl-5-(p-tolyl)-4h-1,2,4-triazol-3-yl)thio)acetohydrazide is closely related to a nitrogen-containing heterocyclic scaffold, an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

CATO supplies 2-((4-Ethyl-5-(p-tolyl)-4h-1,2,4-triazol-3-yl)thio)acetohydrazide (CAS 893726-73-3), a certified reference material (molecular formula C13H17N5OS, MW 291.37 g/mol) for analytical method development and quality control.

The molecular framework of 2-((4-Ethyl-5-(p-tolyl)-4h-1,2,4-triazol-3-yl)thio)acetohydrazide (C13H17N5OS) 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 the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).

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 2-((4-Ethyl-5-(p-tolyl)-4h-1,2,4-triazol-3-yl)thio)acetohydrazide 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.
