Chemical Structure

4-(5-chlorothiophen-2-yl)-3-(thiophen-2-yl)-2,5-dihydrofuran-2-one CAS 748778-73-6 chemical structure

Description

The molecular framework of 4-(5-chlorothiophen-2-yl)-3-(thiophen-2-yl)-2,5-dihydrofuran-2-one (C12H7ClO2S2) is characterized by a sulfone group, a carboxylic acid group, 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 high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

4-(5-chlorothiophen-2-yl)-3-(thiophen-2-yl)-2,5-dihydrofuran-2-one (CAS 748778-73-6) is a high-purity analytical reference standard with the molecular formula C12H7ClO2S2 and a molecular weight of 282.77 g/mol.
