Chemical Structure
Description
The molecular framework of 2-[2-(2-{4-[2-(1,3-dioxo-2,3-dihydro-1H-isoindol-2-yl)ethyl]-1,3-thiazol-2-yl}-1,3-thiazol-4-yl)ethyl]-2,3-dihydro-1H-isoindole-1,3-dione (C26H18N4O4S2) is characterized by a steroid core, an amide group, a sulfone 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.
