5-Chloro-4-methylthiophene-2-sulfonyl Chloride (CAS 1353435-17-2), molecular formula C5H4Cl2O2S2 and molecular weight 231.12 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 5-Chloro-4-methylthiophene-2-sulfonyl Chloride (C5H4Cl2O2S2) is characterized by a sulfone group, a carboxylic acid 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. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
