PHYSICAL STATE; APPEARANCE:
WHITE SOLID IN VARIOUS FORMS.

CHEMICAL DANGERS:
The substance decomposes on heating at 210C and on burning producing toxic and corrosive gases including nitrogen oxides. Reacts bases, strong acids, strong oxidants.

OCCUPATIONAL EXPOSURE LIMITS:
TLV not established.
MAK not established.
ROUTES OF EXPOSURE:
The substance can be absorbed into the body by ingestion.

INHALATION RISK:
Evaporation at 20C is negligible; a nuisance-causing concentration of airborne particles can, however, be reached quickly.

PHYSICAL PROPERTIES
Melting point: 135C
