Chemical Structure
Description
The occurrence of N,N-Dimethylthiophene-3-sulfonamide is closely related to an amide group, a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
CATO supplies N,N-Dimethylthiophene-3-sulfonamide (CAS 153439-45-3), a certified reference material (molecular formula C6H9NO2S2, MW 191.27 g/mol) for analytical method development and quality control.
Owing to an amide group, a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, N,N-Dimethylthiophene-3-sulfonamide is typically white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 191.27 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
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 N,N-Dimethylthiophene-3-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.
