Chemical Structure
Description
The molecular framework of (E)-2-(4-Chlorophenyl)ethylenesulfonyl chloride (C8H6Cl2O2S) 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 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).
(E)-2-(4-Chlorophenyl)ethylenesulfonyl chloride (CAS 52147-98-5), molecular formula C8H6Cl2O2S and molecular weight 237.10 g/mol, is a CATO reference standard with documented purity and traceability.
