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.
2-(4-Chlorophenyl)-1-methoxy-1H-imidazo[4,5-b]pyridine (CAS 339010-07-0), molecular formula C13H10ClN3O and molecular weight 259.69 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 2-(4-Chlorophenyl)-1-methoxy-1H-imidazo[4,5-b]pyridine (C13H10ClN3O) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, chlorine 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. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
As a certified reference material (CRM), 2-(4-Chlorophenyl)-1-methoxy-1H-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.
