Chemical Structure
Description
The molecular framework of 1,1'-((1,4-Phenylenebis(oxy))bis(4,1-phenylene))bis(1H-pyrrole-2,5-dione) (C26H16N2O6) 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.
