Chemical Structure
Description
The molecular framework of 4,4′-[Methylenebis(4,1-phenylenenitrilomethylidyne)]bis[2-methoxyphenol] (C29H26N2O4) 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. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
