Chemical Structure
Description
As a certified reference material (CRM), 6-Bromo-4-chloro-3-isopropyl-3H-imidazo[4,5-c]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.
6-Bromo-4-chloro-3-isopropyl-3H-imidazo[4,5-c]pyridine (CAS 2416917-56-9), molecular formula C9H9BrClN3 and molecular weight 274.54 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 6-Bromo-4-chloro-3-isopropyl-3H-imidazo[4,5-c]pyridine (C9H9BrClN3) is characterized by a nitrogen-containing heterocyclic scaffold, a nitrile group, chlorine/bromine 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. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
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.
