Description
As a certified reference material (CRM), 3-Iodo-4-(isopropylsulfonyl)-5-(methylthio)thiophene-2-carboxylic acid meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
CATO supplies 3-Iodo-4-(isopropylsulfonyl)-5-(methylthio)thiophene-2-carboxylic acid (CAS 175202-14-9), a certified reference material (molecular formula C9H11IO4S3, MW 406.28 g/mol) for analytical method development and quality control.
3-Iodo-4-(isopropylsulfonyl)-5-(methylthio)thiophene-2-carboxylic acid (C9H11IO4S3) contains a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, iodine 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.
