Chemical Structure
Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
5-Aminothiophene-2-carboxamide (CAS 763068-76-4), molecular formula C5H6N2OS and molecular weight 142.18 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage, 5-Aminothiophene-2-carboxamide is typically off-white to pale yellow liquid. Its solid-state physicochemical attributes — including a molecular weight of 142.18 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).
As a certified reference material (CRM), 5-Aminothiophene-2-carboxamide 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.
