Chemical Structure
Description
The molecular framework of Ethyl 1-methyl-4-((3-(trifluoromethyl)benzyl)amino)-1H-pyrazolo[3,4-b]pyridine-5-carboxylate (C18H17F3N4O2) 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. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
