IMPORTANT DATA

Physical State; Appearance
PALE YELLOW, ODOURLESS POWDER.

Chemical dangers
The substance decomposes on burning producing toxic and corrosive gases including carbon oxides, nitrogen oxides, sulfur oxides.

Occupational exposure limits
TLV not established.
MAK not established.

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

Inhalation risk
Evaporation at 20°C is negligible; a nuisance-causing concentration of airborne particles can, however, be reached quickly.

Effects of short-term exposure
The substance may irritate the eyes, the skin and the respiratory tract.

Effects of long-term or repeated exposure
Repeated or prolonged contact may cause skin sensitization.

PHYSICAL PROPERTIES	ENVIRONMENTAL DATA
Melting point: 180°C Relative density (water = 1): 1.5 Solubility in water: none Octanol/water partition coefficient as log Pow: 4.5	It is strongly advised not to let the chemical enter into the environment because it persists in the environment.

NOTES

Insufficient data are available on the effect of this substance on human health, therefore utmost care must be taken.
