Chemical Structure
Description
2-((4-Fluorophenyl)thio)-N-(5-(isoxazol-5-yl)-1,3,4-oxadiazol-2-yl)acetamide (CAS 952874-06-5), molecular formula C13H9FN4O3S and molecular weight 320.30 g/mol, is a CATO reference standard with documented purity and traceability.
2-((4-Fluorophenyl)thio)-N-(5-(isoxazol-5-yl)-1,3,4-oxadiazol-2-yl)acetamide (C13H9FN4O3S) contains a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, fluorine substitution. It is notably hygroscopic, halogen substitution raises its density and boiling point, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
As a certified reference material (CRM), 2-((4-Fluorophenyl)thio)-N-(5-(isoxazol-5-yl)-1,3,4-oxadiazol-2-yl)acetamide 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.
