Thiosemicarbazide (CAS: 79-19-6) is a dithiocarbamide compound is used as a chemical intermedialte for pharmaceuticals and herbicides, pesticides; as a reagent for ketones and certain metals; It is involved in the detection of metals; in certain photography and dye operations; as a rodenticide.
Thiosemicarbazide is used as an analytical reagent.
Thiosemicarbazide is an intermediate for the preparation of carbamate insecticide zosaparib and thiadiazole fungicides and rodenticides, and can also be used in the synthesis of anti-tuberculosis drugs such as amidothiuramide and sulfa drugs, rubber additives and synthetic resin additives, it can also be used as an analytical reagent for the quantification of chromium and the identification of aldehydes and ketones.
Thiosemicarbazide is generally condensed with aldehydes or ketones to synthesize wide range of thiosemicarbazones. It can be used to build a variety of heterocycles and bioactive molecules.
When heated to decomposition, very toxic fumes of sulfur oxides and nitrogen oxides are emitted.
