IMPORTANT DATA
Physical State; Appearance
AMBER VISCOUS LIQUID. 

Physical dangers
 

Chemical dangers
Decomposes on heating. This produces toxic fumes including hydrogen bromide and bromine. 

Occupational exposure limits
TLV (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 short-term exposure
 

Effects of long-term or repeated exposure
The substance may have effects on the liver. 


PHYSICAL PROPERTIES ENVIRONMENTAL DATA
Decomposes at 200-300°C
Melting point: -7 - -3°C
Relative density (water = 1): 2.25-2.28
Solubility in water, g/100ml at 20°C: 0.0013 (very poor)
Vapour pressure 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.
Technical pentabromodiphenyl ether is a mixture of tetra-, penta-, and hexabromodiphenyl ethers.
