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 5-((4-Chlorophenyl)thio)-N-(3-(trifluoromethyl)phenyl)-1,2,3-thiadiazole-4-carboxamide (CAS 303151-35-1), a certified reference material (molecular formula C16H9ClF3N3OS2, MW 415.84 g/mol) for analytical method development and quality control.
Based on its molecular formula C16H9ClF3N3OS2, 5-((4-Chlorophenyl)thio)-N-(3-(trifluoromethyl)phenyl)-1,2,3-thiadiazole-4-carboxamide contains a nitrogen-containing heterocyclic scaffold, an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage, fluorine/chlorine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 415.84 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
