4-Fluoro-3-(2-thiomethylphenyl)propiophenone CAS 898754-69-3

Description

Compared with other compounds in its class, the molecular weight of 274.35 g/mol gives 4-Fluoro-3-(2-thiomethylphenyl)propiophenone distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

4-Fluoro-3-(2-thiomethylphenyl)propiophenone (CAS 898754-69-3), molecular formula C16H15FOS and molecular weight 274.35 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of 4-Fluoro-3-(2-thiomethylphenyl)propiophenone (C16H15FOS) is characterized by sulfur-containing functionality, a hydroxyl group, an ether linkage, fluorine substitution, a polycyclic aromatic system. 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 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.
