Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 344.25 g/mol gives 3-(4-bromobenzyl)-2-ethyl-5,7-dimethyl-3H-imidazo[4,5-b]pyridine distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
3-(4-bromobenzyl)-2-ethyl-5,7-dimethyl-3H-imidazo[4,5-b]pyridine (CAS 154553-72-7), molecular formula C17H18BrN3 and molecular weight 344.25 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 3-(4-bromobenzyl)-2-ethyl-5,7-dimethyl-3H-imidazo[4,5-b]pyridine (C17H18BrN3) is characterized by a nitrogen-containing heterocyclic scaffold, a nitrile group, bromine 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.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
As a certified reference material (CRM), 3-(4-bromobenzyl)-2-ethyl-5,7-dimethyl-3H-imidazo[4,5-b]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.
