Chemical Structure
Description
The molecular framework of 3-(3-Chlorophenyl)-1-(2-thienyl)-2-propen-1-one (C13H9ClOS) is characterized by sulfur-containing functionality, a hydroxyl group, an ether linkage, chlorine substitution, an aromatic ring system. 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).
3-(3-Chlorophenyl)-1-(2-thienyl)-2-propen-1-one (CAS 18003-31-1) is a high-purity analytical reference standard with the molecular formula C13H9ClOS and a molecular weight of 248.73 g/mol.
