Chemical Structure
Description
2-((5,7-Dibromobenzo[c][1,2,5]thiadiazol-4-yl)oxy)acetic acid (C8H4Br2N2O3S) contains a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, bromine 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 presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
2-((5,7-Dibromobenzo[c][1,2,5]thiadiazol-4-yl)oxy)acetic acid (CAS 91982-81-9), molecular formula C8H4Br2N2O3S and molecular weight 368.00 g/mol, is a CATO reference standard with documented purity and traceability.
