2-(5-Fluoro-2-methoxyphenyl)-2-oxoacetic acid CAS 1094355-95-9

Description

The molecular framework of 2-(5-Fluoro-2-methoxyphenyl)-2-oxoacetic acid (C9H7FO4) is characterized by a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine substitution, an aromatic ring system. In reversed-phase chromatography, its retention is governed primarily by the polarity and ionization state of its functional 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).

2-(5-Fluoro-2-methoxyphenyl)-2-oxoacetic acid (CAS 1094355-95-9) is a high-purity analytical reference standard with the molecular formula C9H7FO4 and a molecular weight of 198.15 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.
