5-methoxybenzothiophene-3-sulfonyl chloride (CAS 1158208-28-6), molecular formula C9H15ClO3S2 and molecular weight 270.80 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 5-methoxybenzothiophene-3-sulfonyl chloride (C9H15ClO3S2) 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.
