5-((2,3-Dimethylphenoxy)methyl)-4-ethyl-4H-1,2,4-triazole-3-thiol (CAS 669705-44-6), molecular formula C13H17N3OS and molecular weight 263.36 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 5-((2,3-Dimethylphenoxy)methyl)-4-ethyl-4H-1,2,4-triazole-3-thiol (C13H17N3OS) 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. 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.
