Chemical dangers Reacts with strong reducing agents. This generates heat and flammable/explosive gas (hydrogen - see ICSC 0001).
Molecular mass: 170.1
Sublimation point: 210°C Relative density (water = 1): 1.7 Solubility in water, g/100ml: 1.1 (moderate) Octanol/water partition coefficient as log Pow: 0.7
EXPOSURE & HEALTH EFFECTS
Routes of exposure The substance can be absorbed into the body by ingestion.
Effects of short-term exposure See Notes.
Inhalation risk Evaporation at 20°C is negligible; a harmful concentration of airborne particles can, however, be reached quickly.
Effects of long-term or repeated exposure See Notes.
OCCUPATIONAL EXPOSURE LIMITS
Insufficient data are available on the effect of this substance on human health, therefore utmost care must be taken.
