Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 5-((4-Chlorophenyl)thio)-N-(4-fluorophenyl)-1,2,3-thiadiazole-4-carboxamide.
5-((4-Chlorophenyl)thio)-N-(4-fluorophenyl)-1,2,3-thiadiazole-4-carboxamide (CAS 338791-89-2), molecular formula C15H9ClFN3OS2 and molecular weight 365.83 g/mol, is a CATO reference standard with documented purity and traceability.
5-((4-Chlorophenyl)thio)-N-(4-fluorophenyl)-1,2,3-thiadiazole-4-carboxamide (C15H9ClFN3OS2) contains a nitrogen-containing heterocyclic scaffold, an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage, fluorine/chlorine substitution. Halogen substitution raises its density and boiling point, its high carbon-to-hydrogen ratio confers good lipid solubility; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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), 5-((4-Chlorophenyl)thio)-N-(4-fluorophenyl)-1,2,3-thiadiazole-4-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.
