Chemical Structure
Description
The molecular framework of 1-([1,1'-Biphenyl]-4-yl)-3-((4-bromophenyl)sulfonyl)propan-1-one (C21H17BrO3S) is characterized by a steroid core, a sulfone group, a hydroxyl group, an ether linkage, bromine 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 aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
