Description
- General description: Urea is a colorless, odorless solid. It has prism-like crystals. It forms insoluble nitrate salts with nitric acid and oxalate salts with oxalic acid. On reaction with alkanes or substituted alkanes, it affords crystal-lattice inclusion compounds.[1]Urea can be prepared from ammonia and carbon-dioxide, via Haber-Bosch process.[2] It can also be used to prepare urea-formaldehyde resins, via condensation reaction.[3]
- Application: Urea has been used in the following studies:Synthesis of SnO2 nanoparticles.[4] Synthesis of urethanes, ureides and semicarbazides.[1]Denaturation of protein isolated from Saccharomyces cerevisiae Y15696 strain[5]Protein electrophoretic studies.[6]
