Thioacetamide is a sulfur-containing organic compound used in chemical synthesis, particularly in the production of pharmaceuticals and dyes. It serves as a reagent in analytical chemistry and as a precursor in the synthesis of other compounds. In qualitative analysis it is a convenient substitute for gaseous hydrogen sulfide, and it is also a building block for heterocycles such as benzothiazolones. Available in powder form, it has a molecular weight of 75.13 g/mol, a molecular formula of C2H5NS, and is stored at ambient temperature. It carries the signal word Danger because it may cause cancer (H350), and it is also harmful if swallowed, causes skin and serious eye irritation, and is harmful to aquatic life with long lasting effects. Molekula supplies Thioacetamide from research to bulk quantities with full documentation and ISO 9001:2015 traceability.
