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.
1-((2,4-Dichlorobenzyl)oxy)-2-phenyl-1H-imidazo[4,5-b]pyridine (CAS 339010-03-6) is a high-purity analytical reference standard with the molecular formula C19H13Cl2N3O and a molecular weight of 370.23 g/mol.
The molecular framework of 1-((2,4-Dichlorobenzyl)oxy)-2-phenyl-1H-imidazo[4,5-b]pyridine (C19H13Cl2N3O) is characterized by a steroid core, 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 high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
