Chemical Structure
Description
The molecular framework of Methyl (2E)-3-(4-chlorophenyl)-2-(4-methoxybenzenesulfonyl)prop-2-enoate (C17H15ClO5S) is characterized by a flavonoid core, a sulfone group, a hydroxyl group, an ether linkage, chlorine substitution. In reversed-phase chromatography, its retention is governed primarily by the polarity and ionization state of its functional groups, 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).
Methyl (2E)-3-(4-chlorophenyl)-2-(4-methoxybenzenesulfonyl)prop-2-enoate (CAS 1564076-29-4) is a high-purity analytical reference standard with the molecular formula C17H15ClO5S and a molecular weight of 366.82 g/mol.
