Chemical Structure
Description
The molecular framework of 3-[6-(5-aminopent-1-ynyl)-1-oxo-isoindolin-2-yl]piperidine-2,6-dione (C18H19N3O3) is characterized by a steroid core, an amide group, a hydroxyl group, an ether linkage. 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.
