Chemical Structure
Description
2-(3-Chloropropanamido)thiophene-3-carboxamide (CAS 929973-98-8), molecular formula C8H9ClN2O2S and molecular weight 232.69 g/mol, is a CATO reference standard with documented purity and traceability.
2-(3-Chloropropanamido)thiophene-3-carboxamide (C8H9ClN2O2S) contains a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, chlorine substitution. 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. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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 2-(3-Chloropropanamido)thiophene-3-carboxamide 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.
