Chemical Structure
Description
5-((4-Chlorophenyl)thio)thiophene-2-sulfonamide (CAS 63031-81-2), molecular formula C10H8ClNO2S3 and molecular weight 305.82 g/mol, is a CATO reference standard with documented purity and traceability.
5-((4-Chlorophenyl)thio)thiophene-2-sulfonamide (C10H8ClNO2S3) contains a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, chlorine substitution. Halogen substitution raises its density and boiling point, its high carbon-to-hydrogen ratio confers good lipid solubility, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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.
CATO manufactures 5-((4-Chlorophenyl)thio)thiophene-2-sulfonamide under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
