Description
N-(2,3-Dihydrobenzo[b][1,4]dioxin-6-yl)-2-((3-(pyridin-4-yl)-[1,2,4]triazolo[4,3-b]pyridazin-6-yl)thio)acetamide (C20H16N6O3S) contains a steroid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage. It is notably hygroscopic, 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).
