4-(2,3-Dihydrobenzo[b][1,4]dioxin-6-yl)-3-((5-nitro-thiazol-2-yl)thio)-1H-1,2,4-triazol-5(4H)-one (CAS 883065-90-5) is a high-purity analytical reference standard with the molecular formula C13H9N5O5S2 and a molecular weight of 379.37 g/mol.

4-(2,3-Dihydrobenzo[b][1,4]dioxin-6-yl)-3-((5-nitro-thiazol-2-yl)thio)-1H-1,2,4-triazol-5(4H)-one (C13H9N5O5S2) contains a nitrogen-containing heterocyclic scaffold, 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. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
