IMPORTANT DATA
Physical State; Appearance
COLOURLESS CRYSTALS WITH CHARACTERISTIC ODOUR. 

Physical dangers
 

Chemical dangers
Decomposes on burning. This produces toxic fumes of of nitrogen oxides and sulfur oxides. 

Occupational exposure limits
TLV (NOT-ESTABLISHED):. 

Routes of exposure
The substance can be absorbed into the body by inhalation of its aerosol 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
 

Effects of long-term or repeated exposure
The substance may have effects on the liver. This may result in tissue lesions. This substance is possibly carcinogenic to humans. 


PHYSICAL PROPERTIES ENVIRONMENTAL DATA
Melting point: 113-116°C
Solubility in water: good
Flash point: see Notes
Octanol/water partition coefficient as log Pow: -0.46/-0.36  
 

NOTES
The substance is combustible but no flash point is available in literature.
Depending on the degree of exposure, periodic medical examination is suggested.
Card has been partly updated in October 2005.
