NH2CONH
NH2CONH is the chemical formula for urea. Urea is an organic compound with the formula CO(NH2)2. It is a colorless, odorless solid, highly soluble in water and alcohol. Chemically, urea is a diamide of carbonic acid. It is the principal nitrogenous breakdown product of proteins in mammals and other animals, and it is excreted in urine. Urea is also synthesized industrially on a large scale, primarily for use as a nitrogen-release fertilizer. It is the most common nitrogen-containing fertilizer available. Its high nitrogen content, relatively low cost, and ease of handling make it a popular choice for agricultural applications. Beyond fertilizers, urea has various other uses. It is a component in some plastics, adhesives, and cosmetics. It is also used in the production of melamine, a chemical used to make durable plastic materials. In animal feed, urea can be used as a protein supplement. The synthesis of urea from ammonia and carbon dioxide is a major industrial chemical process.
