Chemical Structure
Description
The occurrence of 2-{2-[(5-Chloro-1,2,4-thiadiazol-3-yl)sulfanyl]ethyl}-2,3-dihydro-1h-isoindole-1,3-dione is closely related to a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, chlorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
CATO supplies 2-{2-[(5-Chloro-1,2,4-thiadiazol-3-yl)sulfanyl]ethyl}-2,3-dihydro-1h-isoindole-1,3-dione (CAS 1326815-58-0), a certified reference material (molecular formula C12H8ClN3O2S2, MW 325.79 g/mol) for analytical method development and quality control.
Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, chlorine substitution, 2-{2-[(5-Chloro-1,2,4-thiadiazol-3-yl)sulfanyl]ethyl}-2,3-dihydro-1h-isoindole-1,3-dione is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 325.79 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
