Chemical Structure
Description
CATO supplies 5-Bromo-n-butylthiophene-2-sulfonamide (CAS 641607-86-5), a certified reference material (molecular formula C8H12BrNO2S2, MW 298.22 g/mol) for analytical method development and quality control.
5-Bromo-n-butylthiophene-2-sulfonamide (C8H12BrNO2S2) contains an amide group, a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, bromine substitution. Halogen substitution raises its density and boiling point, 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-Bromo-n-butylthiophene-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.
