IMPORTANT DATA
Physical State; Appearance
LIGHT YELLOW LIQUID. 

Physical dangers
 

Chemical dangers
Decomposes on heating and on burning. This produces toxic fumes including nitrogen oxides. 

Occupational exposure limits
TLV (NOT-ESTABLISHED):. 

Routes of exposure
The substance can be absorbed into the body through the skin. 

Inhalation risk
A harmful contamination of the air will not or will only very slowly be reached on evaporation of this substance at 20°C; on spraying or dispersing, however, much faster. 

Effects of short-term exposure
The substance is irritating to the skin, eyes and respiratory tract. 

Effects of long-term or repeated exposure
