Chemical Structure
Description
The molecular framework of (3-Chloro-5-fluorophenyl)(2,5-difluorobenzyl)sulfane (C13H8ClF3S) is characterized by sulfur-containing functionality, fluorine/chlorine substitution, an aromatic ring 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. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
