UREA appears as a white crystalline powder, which is highly soluble in water, allowing for easy preparation of solutions for laboratory use. The melting point of urea is approximately 132.7 °C, and it decomposes at higher temperatures, making it stable under normal laboratory conditions. The density of urea is about 1.32 g/cm³, and it has a boiling point of 165 °C at 1 atm. Urea has a neutral pH when dissolved in water, typically around 6-7, and it does not exhibit any significant odor, which is advantageous for laboratory environments.
