Chemical Structure
Description
CATO supplies 3-Bromo-8-phenylimidazo[1,2-a]pyridine (CAS 104271-47-8), a certified reference material (molecular formula C13H9BrN2, MW 273.13 g/mol) for analytical method development and quality control.
The molecular framework of 3-Bromo-8-phenylimidazo[1,2-a]pyridine (C13H9BrN2) 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. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
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.
