AMMONIUM CARBAMATE

Chemical properties

crystal(s) powder(s); ammonia odor; white; rhomb; very volatile; forms urea when heated; made from liquid NH3 and solid CO2; used as a fertilizer [HAW93] [MER06]

Chemical properties

Ammonium carbamate is a colorless crystalline powder or white powder. Ammonia-like odor. The odor threshold is 5 ppm as NH3 (detection) and 46.8 ppm as NH3 (recognition).

The Uses of AMMONIUM CARBAMATE

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.

The Uses of AMMONIUM CARBAMATE

Ammoniating agent, less vigorous than NH3.

What are the applications of Application

Ammonium carbamate is necessary for both the urea cycle and the production of pyrimidines

General Description

A white crystalline solid used as a fertilizer. The primary hazard is the threat to the environment. Immediate steps should be taken to limit its spread to the environment.

Air & Water Reactions

Water soluble.

Reactivity Profile

AMMONIUM CARBAMATE is a carbamate salt. Carbamates are chemically similar to, but more reactive than amides. Like amides they form polymers such as polyurethane resins. Carbamates are incompatible with strong acids and bases, and especially incompatible with strong reducing agents such as hydrides. Flammable gaseous hydrogen is produced by the combination of active metals or nitrides with carbamates. Strongly oxidizing acids, peroxides, and hydroperoxides are incompatible with carbamates. AMMONIUM CARBAMATE is unstable in an alkaline media . AMMONIUM CARBAMATE is incompatible with the following: Strong oxidizers, strongly alkaline pesticides . Moderate fire and explosion hazards when exposed to heat or flame [USCG, 1999].
