IMPORTANT DATA
Physical State; Appearance Routes of exposure
COLOURLESS TO YELLOW SOLID IN VARIOUS FORMS The substance can be absorbed into the body by inhalation and
by ingestion.
Chemical dangers
Inhalation risk
The substance decomposes on burning producing toxic fumes.
Evaporation at 20掳C is negligible; a harmful concentration of
airborne particles can, however, be reached quickly when
Occupational exposure limits
dispersed, especially if powdered.
TLV not established.
MAK: Carcinogen category: 2; (DFG 2003).
Effects of short-term exposure
The substance may cause effects on the blood, resulting in the
formation of methaemoglobin. Medical observation is indicated.
The effects may be delayed.
PHYSICAL PROPERTIES
Boiling point: 304掳C Vapour pressure, kPa at 25掳C: 0.000032
