Chemical Structure
Description
The molecular framework of 5-Chloro-3-iodo-1-(4-methylbenzenesulfonyl)-1H-pyrrolo[2,3-b]pyridine (C14H10ClIN2O2S) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, chlorine/iodine substitution. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), 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).
5-Chloro-3-iodo-1-(4-methylbenzenesulfonyl)-1H-pyrrolo[2,3-b]pyridine (CAS 1241675-24-0) is a high-purity analytical reference standard with the molecular formula C14H10ClIN2O2S and a molecular weight of 432.66 g/mol.
