Properties: Thiourea is white grain, lustrous crystal, bitter, specific gravity of 1.406, melting point: 174-177degree
Use: Thiourea is mainly used to produce Thiourea Dioxide. It is widely used in medicine (Sulfathiazole, Methylthiouracil, niridazole and Fluorouracil), pesticide (insecticide, bactericide, acaricide, herbicide and virus prevention and cure and so on), chemical fertilizer (nitrogenous fertilizer synergist), silk making, agriculture and metal mine choosing. Petroleum and so on.
Analytical reagent. Used for bismuth, osmium, rhodium, selenium, tellurium, lead, the determination of nitrite, etc. Measurement osmic complex indicator.
Packing: 25 kg/cardboard barrels or according to the customer request.
Storage: kept in dry, dark and ventilating place.
