Chemical Structure
Description
The molecular framework of 4-Iodo-1h-pyrrole-2-carboxylicacid (C5H4INO2) is characterized by an amide group, a carboxylic acid 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. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
