Chemical Structure
Description
The occurrence of 4-(6-Bromo-3H-imidazo[4,5-b]pyridin-2-yl)benzonitrile is closely related to a nitrogen-containing heterocyclic scaffold, a nitrile group, bromine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
4-(6-Bromo-3H-imidazo[4,5-b]pyridin-2-yl)benzonitrile (CAS 662113-04-4), molecular formula C13H7BrN4 and molecular weight 299.13 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 4-(6-Bromo-3H-imidazo[4,5-b]pyridin-2-yl)benzonitrile (C13H7BrN4) 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. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
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), 4-(6-Bromo-3H-imidazo[4,5-b]pyridin-2-yl)benzonitrile 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.
