Chemical Structure
Description
The molecular framework of 4-(2H-1,3-Benzodioxol-5-yl)-2-[(E)-2-(2-fluorophenyl)ethenyl]-5-oxo-5H-indeno[1,2-b]pyridine-3-carbonitrile (C28H15FN2O3) is characterized by a steroid core, an amide group, a hydroxyl group, an ether linkage, 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.
