Ammonium carbamate (NH4NH2CO2)-Powder

Characteristic




Ammonium carbamate is an inorganic compound with the formula NH4[H2NCO2]. It is a white solid that is extremely soluble in water, less so in alcohol. Ammonium carbamate can be formed by the reaction of ammonia with carbon dioxide, and will slowly decompose to those gases at ordinary termperatures and pressures.

Application




Ammonium carbamate is used in the preparation of fertilizers. It acts as an ammoniating agent. It plays an important role in the formation of carbamoyl phosphate, which is essential for urea cycle and pyrimidines production. In addition to this, it is used in the preparation of trimethylsilyl carbamate.
