Chemical Structure
Description
The molecular framework of 1-(3,5-Dichlorophenyl)-5-(4-methanesulfonylphenyl)-2-methyl-1H-pyrrole-3-carbaldehyde (C19H15Cl2NO3S) is characterized by a steroid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage, chlorine 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).
