item Agriculture grade Urea CAS no. 57-13-6 Other name Carbamide MF CH4N2O EINECS 200-315-5 Place of Origin China Purity â?¥46% Appearance white granule Application fertilizer Size 0.85-2.8mm, 1.18-3.35mm, 2.00-4.75mm, 4.00-8.00mm Applications 1.Medical field Dermatology uses certain agents containing urea to increase the humidity of the skin. Non-surgical removal of nails uses occlusive dressings that contain 40% urea. 2.Agriculture Urea is a highly concentrated nitrogen fertilizer, which is a neutral fast-acting fertilizer, and can also be used to produce a variety of compound fertilizers. No harmful substances remain in the soil, and there are no adverse effects after long-term application. Animal husbandry can be used as feed for ruminants. However, if the temperature is too high in granulation, a small amount of biuret will be produced, also known as biuret, which has an inhibitory effect on crops. China stipulates that the content of urea biuret for fertilizer should be less than 0.5%. When the content of biuret is more than 1%, it can not be used as seed fertilizer, seedling fertilizer and foliar fertilizer, and the urea content in other application periods should not be too much or too concentrated. 3.Industrial sector It can be used in large quantities as a raw material for the production of melamine, urea-formaldehyde resin, hydrazine hydrate, tetracycline, caffeine, reduced brown BR, phthalocyanine blue B, phthalocyanine blue Bx, monosodium glutamate and other products. 4.Laboratory applications Urea is very effective at denaturing proteins, especially non-covalently bonded proteins. This feature can improve the solubility of certain proteins at concentrations of up to 10 mol/volume. Urea can also be used to make urea nitrate.
