IMPORTANT DATA
Physical State; Appearance Routes of exposure
COLOURLESS LIQUID, WITH CHARACTERISTIC ODOUR. The substance can be absorbed into the body by inhalation of its
aerosol and by ingestion.
Chemical dangers
Inhalation risk
The substance can presumably form explosive peroxides. Reacts
violently with strong oxidants. No indication can be given about the rate in which a harmful
concentration in the air is reached on evaporation of this
Occupational exposure limits substance at 20/C.
TLV not established.
Effects of long-term or repeated exposure
MAK not established.
Animal tests show that this substance possibly causes toxicity to
human reproduction or development.
