PHYSICAL & CHEMICAL INFORMATION

Physical State; Appearance
COLOURLESS-TO-PALE-YELLOW CRYSTALS WITH CHARACTERISTIC ODOUR. 

Physical dangers
 

Chemical dangers
Decomposes on burning. This produces toxic gases of hydrogen chloride and phosgene. Reacts with strong oxidants. This generates fire and explosion hazard.

EXPOSURE & HEALTH EFFECTS

Routes of exposure
The substance can be absorbed into the body by inhalation of fume and through the skin. 

Effects of short-term exposure
The substance is mildly irritating to the eyes and 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 long-term or repeated exposure
The substance may have effects on the liver. This may result in liver impairment. 


OCCUPATIONAL EXPOSURE LIMITS
TLV: 2 mg/m3, as TWA 

ENVIRONMENT
Bioaccumulation of this chemical may occur in fish. It is strongly advised not to let the chemical enter into the environment. The substance may cause long-term effects in the aquatic environment. 

NOTES
The health effects may vary with the proportion of the different isomers present.
