Chemical Structure
Description
The molecular framework of 5-Chloroimidazo[1,2-a]pyridine, HCl (C7H5ClN2HCl) is characterized by a nitrile group, chlorine substitution, an aromatic ring system. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
5-Chloroimidazo[1,2-a]pyridine, HCl (CAS 3931-68-8) is a high-purity analytical reference standard with the molecular formula C7H5ClN2HCl and a molecular weight of 189.04 g/mol.
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.
