IMPORTANT DATA
Physical State; Appearance
YELLOW CRYSTALS. 

Physical dangers
 

Chemical dangers
Decomposes on heating. This produces nitrogen oxides. 

Occupational exposure limits
TLV (NOT-ESTABLISHED):. 

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

Inhalation risk
Evaporation at 20°C is negligible; a harmful concentration of airborne particles can, however, be reached quickly when dispersed. 

Effects of short-term exposure
The substance is irritating to the eyes, skin and respiratory tract. 

Effects of long-term or repeated exposure
Repeated or prolonged contact with skin may cause dermatitis. This substance is possibly carcinogenic to humans. 


PHYSICAL PROPERTIES ENVIRONMENTAL DATA
Decomposes
Melting point: 114-117 °C
Solubility in water: none
Octanol/water partition coefficient as log Pow: 4.58  
 

NOTES
Environmental effects from the substance have not been investigated adequately.
C. I. 11020, Fast yellow and Solvent yellow 2 are commonly used names.
