Chemical Structure
Description
The molecular framework of 4-Fluoro-3-methoxy-2-nitro-benzoic acid methyl ester (C9H8FNO5) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, fluorine substitution. 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. 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).
CATO supplies 4-Fluoro-3-methoxy-2-nitro-benzoic acid methyl ester (CAS 2305079-63-2), a certified reference material (molecular formula C9H8FNO5, MW 229.16 g/mol) for analytical method development and quality control.
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.
