Description
CATO supplies 5-(Acetamidomethyl)thiophene-2-sulfonyl chloride (CAS 859491-07-9), a certified reference material (molecular formula C7H8ClNO3S2, MW 253.73 g/mol) for analytical method development and quality control.
5-(Acetamidomethyl)thiophene-2-sulfonyl chloride (C7H8ClNO3S2) contains an amide group, a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution, an aromatic ring system. It is notably hygroscopic, 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-(Acetamidomethyl)thiophene-2-sulfonyl chloride 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.
