Chemical Structure
Description
6-Bromo-2-ethyl-3H-imidazo[4,5-b]pyridine (CAS 68175-12-2), molecular formula C8H8BrN3 and molecular weight 226.07 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 6-Bromo-2-ethyl-3H-imidazo[4,5-b]pyridine (C8H8BrN3) is characterized by a nitrogen-containing heterocyclic scaffold, a nitrile group, 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. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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 manufactures 6-Bromo-2-ethyl-3H-imidazo[4,5-b]pyridine under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
