Chemical Structure
Description
The occurrence of 4-Chloro-3-fluorobenzenethiol is closely related to sulfur-containing functionality, fluorine/chlorine substitution, an aromatic ring system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
4-Chloro-3-fluorobenzenethiol (CAS 60811-22-5) is a high-purity analytical reference standard with the molecular formula C6H4ClFS and a molecular weight of 162.61 g/mol.
The molecular framework of 4-Chloro-3-fluorobenzenethiol (C6H4ClFS) is characterized by sulfur-containing functionality, fluorine/chlorine 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. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
