Description

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 supplies 4-(4-(4-Bromophenyl)-5-((2-chlorobenzyl)thio)-4H-1,2,4-triazol-3-yl)pyridine (CAS 477329-78-5), a certified reference material (molecular formula C20H14BrClN4S, MW 457.77 g/mol) for analytical method development and quality control.

Structurally, 4-(4-(4-Bromophenyl)-5-((2-chlorobenzyl)thio)-4H-1,2,4-triazol-3-yl)pyridine (C20H14BrClN4S) contains a nitrogen-containing heterocyclic scaffold, a nitrile group, sulfur-containing functionality, chlorine/bromine substitution. The molecule exhibits a degree of unsaturation (DBE) of 15.0, corresponding to approximately 15 ring(s) or double-bond equivalent(s). With a molecular weight of 457.77 g/mol, it falls into the moderately-high-molecular-weight range. 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).

As a certified reference material (CRM), 4-(4-(4-Bromophenyl)-5-((2-chlorobenzyl)thio)-4H-1,2,4-triazol-3-yl)pyridine 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.
