PHYSICAL & CHEMICAL INFORMATION
Physical State; Appearance ODOURLESS COLOURLESS CRYSTALS. Physical dangers Dust explosion possible if in powder or granular form, mixed with air. Chemical dangers Decomposes on heating and on burning. This produces toxic fumes of nitrogen oxides. The substance is a weak base. Reacts violently with strong acids, strong oxidants, acid chlorides and acid anhydrides. This generates fire and explosion hazard.	Formula: C₂H₄N₄ Molecular mass: 84.1 Decomposes when heated Melting point: 159°C Solubility in water, g/l at 25°C: 280 Octanol/water partition coefficient as log Pow: -0.97 Relative density (water = 1): 1.14 (20°C) Relative vapour density (air = 1): 2.9 Vapour pressure, kPa at 20°C: (negligible)

EXPOSURE & HEALTH EFFECTS

Routes of exposure
The substance can be absorbed into the body by inhalation of its aerosol.

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

Inhalation risk
A nuisance-causing concentration of airborne particles can be reached on spraying.

Effects of long-term or repeated exposure
Tumours have been detected in experimental animals but may not be relevant to humans.

OCCUPATIONAL EXPOSURE LIMITS
TLV: 0.2 mg/m³, as TWA; A3 (confirmed animal carcinogen with unknown relevance to humans). MAK: (inhalable fraction): 0.2 mg/m³; peak limitation category: II(8); skin absorption (H); carcinogen category: 4; pregnancy risk group: C. EU-OEL: 0.2 mg/m³ as TWA

ENVIRONMENT
The substance is toxic to aquatic organisms. This substance does enter the environment under normal use. Great care, however, should be taken to avoid any additional release, for example through inappropriate disposal.

NOTES
Insufficient data are available on the effect of this substance on human health, therefore utmost care must be taken. Do NOT take working clothes home.
