Ammonium carbamate

Ammonium carbamate is an organic compound with the formula NH 4 [H 2 NCO 2] consisting of ammonium NH + 4 and carbamate H 2 NCO − 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 temperatures and pressures.
