IMPORTANT DATA
Physical State; Appearance
ODOURLESS WHITE OR COLOURLESS CRYSTALS. 

Physical dangers
 

Chemical dangers
Decomposes on burning. This produces toxic and corrosive fumes of of nitrogen oxides and chlorine (see ICSC 0126). The solution is corrosive to aluminum, iron and tin. 

Occupational exposure limits
TLV (NOT-ESTABLISHED):. 

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

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 is irritating to the eyes, skin and respiratory tract. 

Effects of long-term or repeated exposure
 


PHYSICAL PROPERTIES ENVIRONMENTAL DATA
Melting point: 151-152°C
