4-((4-Chlorophenyl)thio)-2,3-dihydrothiophene 1,1-dioxide (CAS 339023-41-5), molecular formula C10H9ClO2S2 and molecular weight 260.76 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 4-((4-Chlorophenyl)thio)-2,3-dihydrothiophene 1,1-dioxide (C10H9ClO2S2) 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 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).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
