Physical dangers
 

Chemical dangers
Decomposes above 300°C . This produces ammonia, carbon monoxide, hydrogen chloride and nitrogen oxides. Reacts with oxidants. 

Occupational exposure limits
TLV (NOT-ESTABLISHED):. 

Routes of exposure
The substance can be absorbed into the body by inhalation and by ingestion. 

Inhalation risk
Evaporation at 20°C is negligible; a harmful concentration of airborne particles can, however, be reached quickly when dispersed. 

Effects of short-term exposure
The substance is irritating to the eyes, skin and respiratory tract. The substance may cause effects on the central nervous system. 

Effects of long-term or repeated exposure
 


PHYSICAL PROPERTIES ENVIRONMENTAL DATA
Decomposes at 368-370°C
Density: 1.17 g/cm³
Solubility in water at 20°C: very good 
 

NOTES
Environmental effects from the substance have not been investigated.
