IMPORTANT DATA
Physical State; Appearance
COLOURLESS ODOURLESS HYGROSCOPIC VISCOUS LIQUID. 

Physical dangers
 

Chemical dangers
Reacts violently with strong oxidants and alkalis. This generates fire hazard. 

Occupational exposure limits
TLV (NOT-ESTABLISHED):.
MAK (2b (not established but data is available)): (DFG 2013). 

Routes of exposure
 

Inhalation risk
No indication can be given whether a harmful concentration in the air will be reached. 

Effects of short-term exposure
The substance is mildly irritating to the eyes and respiratory tract. Ingestion of large amounts could cause metabolic acidosis. 

Effects of long-term or repeated exposure
