4-((3,4-Dihydroxybenzylidene)amino)-3-(2-fluorophenyl)-1H-1,2,4-triazole-5(4H)-thione (CAS 577789-70-9), molecular formula C15H11FN4O2S and molecular weight 330.34 g/mol, is a CATO reference standard with documented purity and traceability.
4-((3,4-Dihydroxybenzylidene)amino)-3-(2-fluorophenyl)-1H-1,2,4-triazole-5(4H)-thione (C15H11FN4O2S) 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. 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.
