Chemical Structure
Description
4-Fluoro-3-[(6-fluoroimidazo[1,2-a]pyridine-3-carbonyl)amino]benzoic acid methyl ester (CAS 2088941-82-4) is a high-purity analytical reference standard with the molecular formula C16H11F2N3O3 and a molecular weight of 331.27 g/mol.
Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, fluorine substitution, 4-Fluoro-3-[(6-fluoroimidazo[1,2-a]pyridine-3-carbonyl)amino]benzoic acid methyl ester is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 331.27 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.
As a certified reference material (CRM), 4-Fluoro-3-[(6-fluoroimidazo[1,2-a]pyridine-3-carbonyl)amino]benzoic acid methyl ester meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
