IMPORTANT DATA

Physical State; Appearance
COLOURLESS CRYSTALS. TURNS DARK ON EXPOSURE TO AIR.

Chemical dangers
The substance decomposes on burning producing toxic fumes of nitrogen oxides.

Occupational exposure limits
TLV not established.
MAK: skin absorption (H); sensitization of skin (Sh); Carcinogen category: 2; (DFG 2005).

Routes of exposure
The substance can be absorbed into the body by inhalation of its aerosol or vapour (when in molten state), through the skin and by ingestion.

Inhalation risk
No indication can be given about the rate in which a harmful concentration in the air is reached on evaporation of this substance at 20°C.

Effects of short-term exposure
The substance irritates the eyes, the skin and the respiratory tract. The hot liquid may cause severe skin burns. The substance may cause effects on the liver and blood, resulting in liver damage and formation of methaemoglobin. The effects may be delayed. Medical observation is indicated.

Effects of long-term or repeated exposure
Repeated or prolonged contact may cause skin sensitization. This substance is possibly carcinogenic to humans. May cause genetic damage in humans.

PHYSICAL PROPERTIES	ENVIRONMENTAL DATA
Boiling point: 292°C Melting point: 99°C Relative density (water = 1): see Notes Solubility in water: good Vapour pressure, kPa at 106.5°C: 0.13 Relative vapour density (air = 1): 4.2 Relative density of the vapour/air-mixture at 20°C (air = 1): 1.00 Flash point: 149°C Octanol/water partition coefficient as log Pow: 0.35	The substance is harmful to aquatic organisms.

NOTES

May be handled and shipped in the molten state. Density of the solid is unknown in literature, but density of the liquid (water = 1) at 100°C is 1.045.
Depending on the degree of exposure, periodic medical examination is suggested.
Specific treatment is necessary in case of poisoning with this substance; the appropriate means with instructions must be available.
