Chemical Structure
Description
2-Ethyl-N-(5-((2-((2-fluorophenyl)amino)-2-oxoethyl)thio)-1,3,4-thiadiazol-2-yl)butanamide (C16H19FN4O2S2) 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).
