Ammonium carbamate
I. Structural Formula:NH4CO2NH2
II. Physical and Chemical Properties:
Ammonium carbamate is an important chemical raw material in a very wide range of use, made of ammonium bicarbonate and carbamic acid (commonly known as complex salt). It is white and translucent solid.
Ammonium carbamate is used for the production of pharmaceutical pharmaceuticals, pharmaceutical reagents, fermentation promoters and electronic components and so on. It is a valuable ammoniating agent. It can be used as analytical pure of chemical reagent for spot analysis of potassium, radium and thorium, and also can be a chromatography reagent and derive into kinds of carbonate products. It is insoluble in alcohol and hygroscopic, with specific gravity of 1.56 and melting point of 58°C, It will release ammonia odor in moisture and damp condition, and easy to weather in the air.
