Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 3-((4-Bromobenzyl)thio)-5-(((2,6-dichlorobenzyl)thio)methyl)-4-phenyl-4H-1,2,4-triazole.
3-((4-Bromobenzyl)thio)-5-(((2,6-dichlorobenzyl)thio)methyl)-4-phenyl-4H-1,2,4-triazole (CAS 344271-28-9), molecular formula C23H18BrCl2N3S2 and molecular weight 551.35 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to a nitrogen-containing heterocyclic scaffold, a nitrile group, sulfur-containing functionality, chlorine/bromine substitution, 3-((4-Bromobenzyl)thio)-5-(((2,6-dichlorobenzyl)thio)methyl)-4-phenyl-4H-1,2,4-triazole is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 551.35 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.
As a certified reference material (CRM), 3-((4-Bromobenzyl)thio)-5-(((2,6-dichlorobenzyl)thio)methyl)-4-phenyl-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.
