Ammonium carbamate is widely used in the production of urea, a key component in fertilizers, which enhances crop growth by providing a rich source of nitrogen. It also plays a role in the synthesis of various chemicals, including pharmaceuticals, plastics, and melamine, where it acts as a precursor or intermediate. In the food industry, it serves as a leavening agent in baked goods, helping dough rise by releasing gas. Additionally, it is utilized in cold packs as a cooling agent due to its endothermic reaction when dissolved in water. It is also used as a conditioner in CO2 separation processes in the petrochemical industry. In laboratory settings, it is used as a reagent for chemical reactions and analysis.
