Based on its molecular formula C8H5N2S3K, 17654-88-5 3-Phenyl-1,3,4-thiadiazolidine-2,5-dithione 2H-1,3,4-Thiadiazole-2-thione, 5-mercapto-3-phenyl- 1,3,4-Thiadiazolidine-2,5-dithione, 3-phenyl- (9CI) delta2-1,3,4-Thiadiazolidine-5-thione, 2-mercapto-4-phenyl- (6CI,8CI) Bismuthiol II Bizmuthiol II [Czech] EINECS 241-636-0 5-Mercapto-3-phenyl-2H-1,3,4-thiadiazole-2-thione 5-Merkapto-3-fenyl-1,3,4-thiadiazol-2-thion draselny [Czech] 3-Phenylbismuthol 5-Merkapto-3-fenyl-1,3,4-thiadiazol-2-thion draselny Bizmuthiol II contains a nitrogen-containing heterocyclic scaffold, a nitrile group, sulfur-containing functionality; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 264.42 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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).
