Description
As a certified reference material (CRM), 5-Cyano-4-methyl-3-phenylthiophene-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.
5-Cyano-4-methyl-3-phenylthiophene-2-carboxamide (CAS 70541-99-0), molecular formula C13H10N2OS and molecular weight 242.30 g/mol, is a CATO reference standard with documented purity and traceability.
Based on its molecular formula C13H10N2OS, 5-Cyano-4-methyl-3-phenylthiophene-2-carboxamide contains a nitrogen-containing heterocyclic scaffold, an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 242.30 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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.
