2-((4-Chlorophenyl)thio)-N-(5-(trifluoromethyl)-1,3,4-thiadiazol-2-yl)acetamide (CAS 339013-81-9) is a high-purity analytical reference standard with the molecular formula C11H7ClF3N3OS2 and a molecular weight of 353.77 g/mol.
Based on its molecular formula C11H7ClF3N3OS2, 2-((4-Chlorophenyl)thio)-N-(5-(trifluoromethyl)-1,3,4-thiadiazol-2-yl)acetamide 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 353.77 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.
