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.
CATO supplies 6-bromo-2-(chloromethyl)-3H-imidazo[4,5-b]pyridine hydrochloride (CAS 1334149-01-7), a certified reference material (molecular formula C7H5BrClN3HCl, MW 282.95 g/mol) for analytical method development and quality control.
Based on its molecular formula C7H5BrClN3HCl, 6-bromo-2-(chloromethyl)-3H-imidazo[4,5-b]pyridine hydrochloride contains a nitrile group, chlorine/bromine substitution, an aromatic ring system; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 282.95 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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.
