1-((4-Bromobenzyl)oxy)-2-(2-chlorophenyl)-1H-imidazo[4,5-b]pyridine CAS 339028-59-0

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 1-((4-Bromobenzyl)oxy)-2-(2-chlorophenyl)-1H-imidazo[4,5-b]pyridine.

1-((4-Bromobenzyl)oxy)-2-(2-chlorophenyl)-1H-imidazo[4,5-b]pyridine (CAS 339028-59-0), molecular formula C19H13BrClN3O and molecular weight 414.68 g/mol, is a CATO reference standard with documented purity and traceability.

1-((4-Bromobenzyl)oxy)-2-(2-chlorophenyl)-1H-imidazo[4,5-b]pyridine (C19H13BrClN3O) contains a steroid core, an amide group, a hydroxyl group, an ether linkage, chlorine/bromine substitution. Halogen substitution raises its density and boiling point, its high carbon-to-hydrogen ratio confers good lipid solubility; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.

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.

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.
