Chemical Structure
Description
The molecular framework of (4R,5R)-4,5-Dihydro-1,3-bis[2-(1-methylethyl)phenyl]-4,5-diphenyl-1H-imidazolium Tetrafluoroborate (C33H35N2BF4) is characterized by a nitrogen-containing heterocyclic scaffold, a nitrile group, fluorine 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.
