Chemical Structure
Description
The molecular framework of 3-(Benzo[4,5]thiazolo[2,3-c][1,2,4]triazol-3-ylthio)-1-benzoylazepan-2-one (C21H18N4O2S2) 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. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
