Ammonium Carbamate is a white, crystalline, water-soluble solid with a characteristic ammonia odor. It is an important intermediate in the industrial production of urea and serves as a versatile reagent in organic synthesis, pharmaceutical manufacturing, and specialized agricultural applications. Unlike ammonium carbonate, ammonium carbamate is the true intermediate in the urea process and decomposes readily into ammonia and carbon dioxide.

Primary Applications of Ammonium Carbamate
Pharmaceutical Intermediate:
Key reagent in the synthesis of pyrimidine derivatives, barbiturates, and sulfamethazine.
Controlled Release of Ammonia & CO₂:
Used in closed systems for calibration gases, fire suppression prototyping, and greenhouse CO₂ enrichment.
Agricultural & Fertilizer Research:
Serves as a slow-release nitrogen source and soil pH modifier in experimental formulations.
Organic Synthesis:
In-situ generation of ammonia for reductive amination and urea derivative preparation.
Deodorizing & Neutralization:
Reacts with acidic odors to form non-volatile salts (used in some industrial air treatment systems).
Polymer & Plastics Industry:
Blowing agent precursor in certain foam manufacturing processes.
Frequently Asked Questions (FAQs)
Does Ammonium Carbamate release ammonia gas at room temperature?
Yes, it slowly sublimes/decomposes at room temperature, releasing ammonia and carbon dioxide. The rate increases significantly above 35–40 °C. Always open containers in a well-ventilated area or fume hood.
Can Ammonium Carbamate be used as a fertilizer?
Yes. It acts as a slow-release nitrogen source because it hydrolyzes and decomposes in soil to release ammonia gradually. It is particularly useful in alkaline soils and for certain greenhouse applications.
Is Ammonium Carbamate stable for long-term storage?
When stored in airtight containers below 25 °C and protected from moisture, it remains stable for years. Exposure to air causes gradual decomposition and ammonia odor.
How should I dispose of Ammonium Carbamate waste?
Dispose according to local regulations for ammonium compounds. Do not heat large quantities in closed containers.
