- PRODUCT NAME: Thiourea MOLECULAR FORMULAR: (NH2)2CS
- Thiourea (also called Thiocarbamide or Sulfourea) is the diamide of thiocarbonic acid that resembles urea but contains sulfur instead of oxygen. Thiourea is the main raw material of producing thiourea dioxide, which presents a white sheen slice, pillar or needle form shining crystallize body. It can dissolves in cold water, ammonium sulphur prussic acid and alcohol, also easily dissolves in hot water, but hardly dissolves in aether.
Thiourea is a fine chemicals product with high additive value,which is widely applied in various industries such as medicine, agriculture, textile, printing-dyeing, chemical, metal-mine-selecting, laundering etc.
It mainly uses in pharmaceutical raw material, bleaching agent in textile dyeing and printing, auxiliary of dyeing and anti-oxidant, and it can be used as rubber accelerator, floating agent, photo developing agent, prexide thiourea, cold wave etc. It is also used in resin compression molding powder electroplatin blue printing and boiler washing. In macromolecule material industry, it is used as catalysis agent and stabilizer of resinic producing, and it is also used in organic synthesization of sensitizing material, and medicine, medical, spicery materials in fine chemicals, and also can be applied in the recycling and separating of heavy metals.
