IMPORTANT DATA
PHYSICAL STATE; APPEARANCE:
WHITE CRYSTALS.

CHEMICAL DANGERS:
The substance decomposes on heating producing toxic fumes including sulfur oxides, nitrogen oxides, hydrogen chloride, phosgene.

OCCUPATIONAL EXPOSURE LIMITS:
TLV: (Inhalable fraction) 5 mg/m as TWA; A3 (confirmed animal carcinogen with unknown relevance to humans); SEN; (ACGIH 2004).
MAK not established.
ROUTES OF EXPOSURE:
The substance can be absorbed into the body by inhalation and through the skin.

INHALATION RISK:
Evaporation at 20C is negligible; a harmful concentration of airborne particles can, however, be reached quickly on spraying or when dispersed, especially if powdered.

EFFECTS OF SHORT-TERM EXPOSURE:
The substance is irritating to the eyes and the skin.

EFFECTS OF LONG-TERM OR REPEATED EXPOSURE:
Repeated or prolonged contact with skin may cause dermatitis. Repeated or prolonged contact may cause skin sensitization.
PHYSICAL PROPERTIES
Melting point (decomposes): 178C
Relative density (water = 1): 1.74
Solubility in water, g/100 ml at 25C: (none)
Octanol/water partition coefficient as log Pow: 2.35
ENVIRONMENTAL DATA
This substance may be hazardous to the environment; special attention should be given to aquatic organisms and soil organisms.
