IMPORTANT DATA
Physical State; Appearance Routes of exposure
WHITE CRYSTALS, TURNS RED ON EXPOSURE TO AIR. The substance can be absorbed into the body by inhalation of
its vapour, through the skin and by ingestion.
Chemical dangers
Inhalation risk
The substance decomposes on burning producing toxic fumes
including nitrogen oxides. Reacts with strong oxidants. A harmful contamination of the air will not or will only very slowly
be reached on evaporation of this substance at 20/C; on
spraying or dispersing, however, much faster.
Occupational exposure limits
TLV: 0.1 mg/m3 as TWA; A4 (not classifiable as a human

resulting in renal failure and formation of methaemoglobin. The
effects may be delayed. Medical observation is indicated.
Effects of long-term or repeated exposure
Repeated or prolonged contact may cause skin sensitization.
The substance may have effects on the kidneys, resulting in
renal failure.
