The molecular framework of 3-(((2,4-Dichlorobenzyl)sulfinyl)methyl)-5-((2,6-dichlorobenzyl)thio)-4-ethyl-4H-1,2,4-triazole (C19H17Cl4N3OS2) is characterized by a steroid core, an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage, chlorine substitution. 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).
3-(((2,4-Dichlorobenzyl)sulfinyl)methyl)-5-((2,6-dichlorobenzyl)thio)-4-ethyl-4H-1,2,4-triazole (CAS 344272-38-4), molecular formula C19H17Cl4N3OS2 and molecular weight 509.30 g/mol, is a CATO reference standard with documented purity and traceability.
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.
As a certified reference material (CRM), 3-(((2,4-Dichlorobenzyl)sulfinyl)methyl)-5-((2,6-dichlorobenzyl)thio)-4-ethyl-4H-1,2,4-triazole 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.
