Chemical Structure
Description
The molecular framework of 5-Chloro-4-(((4-fluorophenyl)thio)methyl)-1-methyl-3-((p-tolylthio)methyl)-1H-pyrazole (C19H18ClFN2S2) is characterized by a nitrogen-containing heterocyclic scaffold, a nitrile group, sulfur-containing functionality, fluorine/chlorine substitution. 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.
