2-(3-Fluoro-4-(methylthio)phenyl)acetic acid CAS 259543-76-5

Description

Compared with other compounds in its class, the molecular weight of 200.23 g/mol gives 2-(3-Fluoro-4-(methylthio)phenyl)acetic acid distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

CATO supplies 2-(3-Fluoro-4-(methylthio)phenyl)acetic acid (CAS 259543-76-5), a certified reference material (molecular formula C9H9FO2S, MW 200.23 g/mol) for analytical method development and quality control.

The molecular framework of 2-(3-Fluoro-4-(methylthio)phenyl)acetic acid (C9H9FO2S) is characterized by a sulfone group, 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 aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

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.
