Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
CATO supplies N-(5-Oxo-4,5-dihydro-1,3,4-thiadiazol-2-yl)benzamide (CAS 33901-26-7), a certified reference material (molecular formula C9H7N3O2S, MW 221.24 g/mol) for analytical method development and quality control.
Based on its molecular formula C9H7N3O2S, N-(5-Oxo-4,5-dihydro-1,3,4-thiadiazol-2-yl)benzamide contains a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 221.24 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).
CATO manufactures N-(5-Oxo-4,5-dihydro-1,3,4-thiadiazol-2-yl)benzamide 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.
