Chemical Structure
Description
The molecular framework of 2-Chloro-4,6-di-p-tolyl-1,3,5-triazine (C17H14ClN3) is characterized by a nitrogen-containing heterocyclic scaffold, a nitrile group, 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. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
2-Chloro-4,6-di-p-tolyl-1,3,5-triazine (CAS 21902-34-1) is a high-purity analytical reference standard with the molecular formula C17H14ClN3 and a molecular weight of 295.77 g/mol.
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), 2-Chloro-4,6-di-p-tolyl-1,3,5-triazine 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.
