N'-((2,6-dichloropyridin-3-yl)methylene)-4-methylbenzenesulfonohydrazide (CAS 1820748-57-9), molecular formula C13H11Cl2N3O2S and molecular weight 344.22 g/mol, is a CATO reference standard with documented purity and traceability.

N'-((2,6-dichloropyridin-3-yl)methylene)-4-methylbenzenesulfonohydrazide (C13H11Cl2N3O2S) contains a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, chlorine 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. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
