Chemical Structure
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 3,4,5-Triiodo-2,6-dimethylpyridine (CAS 98549-80-5), a certified reference material (molecular formula C7H6I3N, MW 484.84 g/mol) for analytical method development and quality control.
The molecular framework of 3,4,5-Triiodo-2,6-dimethylpyridine (C7H6I3N) is characterized by a nitrile group, iodine substitution, an aromatic ring system. 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. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
As a certified reference material (CRM), 3,4,5-Triiodo-2,6-dimethylpyridine 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.
