(S)-6-((4-Chlorophenyl)(1H-1,2,4-triazol-1-yl)methyl)-1-methyl-1H-benzo[d][1,2,3]triazole (CAS 129731-10-8) is a high-purity analytical reference standard with the molecular formula C16H13ClN6 and a molecular weight of 324.77 g/mol.
The molecular framework of (S)-6-((4-Chlorophenyl)(1H-1,2,4-triazol-1-yl)methyl)-1-methyl-1H-benzo[d][1,2,3]triazole (C16H13ClN6) is characterized by a nitrogen-containing heterocyclic scaffold, a nitrile group, chlorine substitution. 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. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
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), (S)-6-((4-Chlorophenyl)(1H-1,2,4-triazol-1-yl)methyl)-1-methyl-1H-benzo[d][1,2,3]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.
