3-Chloro-5-((2-chlorobenzyl)sulfonyl)-1,2,4-thiadiazole CAS 444791-20-2

Description

3-Chloro-5-((2-chlorobenzyl)sulfonyl)-1,2,4-thiadiazole (C9H6Cl2N2O2S2) 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.
