  • Applications

    Ammonium carbamate is primarily an industrial manufacturing intermediate in the production of urea, formed from ammonia and carbon dioxide and subsequently dehydrated to give urea. It is used as a feedstock in the urea production chain for fertilizer, a key nutrient source for agriculture. Additionally, ammonium carbamate is viewed as a precursor to urea-based resins such as urea-formaldehyde resins used in coatings, adhesives, and molded plastics, and it can serve as a carbamoylating reagent in certain organic synthesis routes at laboratory scale.
