1-(4-chloro-6-methyl-1,3,5-triazin-2-yl)-1H-indazole (CAS 2002804-50-2), molecular formula C11H8ClN5 and molecular weight 245.67 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 1-(4-chloro-6-methyl-1,3,5-triazin-2-yl)-1H-indazole (C11H8ClN5) 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. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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), 1-(4-chloro-6-methyl-1,3,5-triazin-2-yl)-1H-indazole 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.
