Description
As a certified reference material (CRM), Ethyl (2-aminothiophene-3-carbonyl)carbamate 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.
Ethyl (2-aminothiophene-3-carbonyl)carbamate (CAS 1171382-99-2), molecular formula C8H10N2O3S and molecular weight 214.24 g/mol, is a CATO reference standard with documented purity and traceability.
Ethyl (2-aminothiophene-3-carbonyl)carbamate (C8H10N2O3S) contains a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage. It is notably hygroscopic, 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.
