Description
The molecular framework of Hydrogen fluoride-pyridine (70% HF) hydrogen fluoride/pyridine hf-pyridine hydrogen fluoride-pyridine hydrogen fluoride pyridine hydrogen fluoride pyridine complex pyridine hydrofluoride hf 55% in pyridine hf 70% in pyridine pyridinium poly(hydrogen fluoride) complex hydrogenfluoride-pyridine pyridinium poly(hydrogen fluoride) pyridinium poly(hydrogenfluoride) 62778-11-4 (C5H11NHF) is characterized by fluorine substitution. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
