Chemical Structure
Description
The molecular framework of 2-Ethoxy-4-formyl-6-iodophenyl 4-acetamidobenzenesulfonate (C17H16INO6S) is characterized by a flavonoid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage, iodine substitution. 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. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
