Product Name:2,5-Dimercapto-1,3,4-thiadiazole
English Name:2,5-Dimercapto-1,3,4-thiadiazole
CAS No.:1072-71-5
Aliases:1,3,4-Thiadiazolidine-2,5-dithione, 2,5-Dimercapto-1-thia-3,4-diazole, Bismuthiol I, Dimercaptothiadiazole
Molecular Formula:C2H2N2S3
Physical Properties:Yellow needle-like crystals. Melting point: 173°C (decomposition). Easily soluble in ether and alkaline solutions, slightly soluble in alcohol, insoluble in water, chloroform, and benzene. Its alkaline solution is unstable, precipitating sulfur upon prolonged storage. Unstable in air and light; should be stored in a nitrogen-filled container protected from light.
Uses:It is used as an analytical reagent, producing a red color with bismuth, brown with copper, and a bright yellow precipitate with lead. It is applied in the colorimetric determination of bismuth and the photometric determination of antimony and palladium. It also serves as an intermediate in the synthesis of cephalosporin pharmaceuticals.
