IMPORTANT DATA
Physical State; Appearance AMBER VISCOUS LIQUID Chemical dangers The substance decomposes on heating producing toxic fumes including hydrogen bromide or bromine. 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, through the skin and by ingestion. Inhalation risk Evaporation at 20°C is negligible; a harmful concentration of airborne particles can, however, be reached quickly on spraying. Effects of long-term or repeated exposure The substance may have effects on the liver.

PHYSICAL PROPERTIES	ENVIRONMENTAL DATA
Boiling point (decomposes): 200-300°C Melting point: -7 - -3°C Relative density (water = 1): 2.25 - 2.28 Solubility in water, g/100 ml at 20°C: 0.0013 (very poor) Vapour pressure, Pa at 21°C: negligible Octanol/water partition coefficient as log Pow: 6.57	The substance is very toxic to aquatic organisms. Bioaccumulation of this chemical may occur along the food chain, for example in seafood.

NOTES

The substance accumulates in fat tissues and can be excreted in breast milk.
