Molecular mass: 110.1
Boiling point: 160°C Relative density (water = 1): 1.00 Solubility in water: none Relative vapour density (air = 1): 3.8 Relative density of the vapour/air-mixture at 20°C (air = 1): 1.03 Flash point: see Notes
EXPOSURE & HEALTH EFFECTS
Routes of exposure The substance can be absorbed into the body by inhalation.
Effects of short-term exposure Exposure above the OEL could cause death. The substance is irritating to the respiratory tract, eyes and skin.
Effects of long-term or repeated exposure
OCCUPATIONAL EXPOSURE LIMITS
TLV: 0.05 ppm as STEL
Insufficient data are available on the effect of this substance on human health, therefore utmost care must be taken. The substance is combustible but no flash point is available in literature. The occupational exposure limit value should not be exceeded during any part of the working exposure.
