Chemical Structure
Description
The occurrence of N-(3-(4-chlorophenyl)imidazo[1,2-a]pyridin-8-yl)-2-fluorobenzamide is closely related to a steroid core, an amide group, a hydroxyl group, an ether linkage, fluorine/chlorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
CATO supplies N-(3-(4-chlorophenyl)imidazo[1,2-a]pyridin-8-yl)-2-fluorobenzamide (CAS 439096-62-5), a certified reference material (molecular formula C20H13ClFN3O, MW 365.79 g/mol) for analytical method development and quality control.
The molecular framework of N-(3-(4-chlorophenyl)imidazo[1,2-a]pyridin-8-yl)-2-fluorobenzamide (C20H13ClFN3O) is characterized by a steroid core, an amide group, a hydroxyl group, an ether linkage, fluorine/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 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.
