Chemical Structure
Description
The molecular framework of 1-(3-Fluoro-4-methoxyphenyl)ethane-1-thiol (C9H11FOS) is characterized by sulfur-containing functionality, 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).
