Thiourea is an organic sulfur-containing compound, molecular formula CH4N2S, white and shiny crystal, bitter taste, density 1.41g/cm, melting point 176 ~ 178oC. It breaks down when it's hotter. Soluble in water, soluble in ethanol when heated, very little soluble in ether. Partial isomerization is performed during melting to form thiocyanurate specific ammonium. It is also used as vulcanization accelerator for rubber and flotation agent for metal minerals, etc. It is formed by the action of hydrogen sulfide with lime slurry to form calcium sulphide, and then with calcium cyanamide (group). Ammonium thiocyanate can also be fused to produce, or the cyanide and hydrogen sulfide produced by the action.

Applications
1. Used to synthesize sulfathiazole, methionine and porcine tablets and other pharmaceutical raw materials.
2. Used as raw materials for dyes and dyeing auxiliaries, resins and plasticizer.
3. It can also be used as a vulcanization accelerator for rubber, a flotation agent for metallic minerals, a catalyst for the preparation of phthalic anhydride and fumaric acid, and as a corrosion inhibitor for metals.
4. In photographic materials, can be used as a developer and toner. It can also be used in electroplating industry.
