Product Description
UREA is a spherical white solid. It is an organic amide molecule containing 46% nitrogen in the form of amine groups. UREA is infinitely soluble in water and is suitable for use an agricultural and forestry fertilizer as well as for industrial applications which require a high quality nitrogen source. It is not a poison to mammals and birds and is a benign and safe chemical to handle. Urea, also known as urea and carbonamide, has a chemical formula of CH4N2O or CO(NH2)2. It is an organic compound composed of carbon, nitrogen, oxygen and hydrogen. It is a white crystal. One of the simplest organic compounds, it is the major nitrogenous end product of the breakdown of protein metabolism in mammals and some fish. As a neutral fertilizer, urea is suitable for a variety of soils and plants. It is easy to store, easy to use, and has little damage to the soil. It is a chemical nitrogen fertilizer with a large amount of use, and it is also the nitrogen fertilizer with the highest nitrogen content. In industry, and carbon dioxide are used to synthesize urea under certain conditions.
