CAS #: 102-71-6
EC Number: 203-049-8
FIRE & EXPLOSION
Combustible. Gives off irritating or toxic fumes (or gases) in a fire.
NO open flames.
Use water in large amounts, alcohol-resistant foam, dry powder, carbon dioxide.
PREVENT GENERATION OF MISTS!
Cough. Sore throat.
Use local exhaust. Use ventilation.
Fresh air, rest.
Remove contaminated clothes. Rinse and then wash skin with water and soap.
Wear safety goggles.
First rinse with plenty of water for several minutes (remove contact lenses if easily possible), then refer for medical attention.
Do not eat, drink, or smoke during work.
Give one or two glasses of water to drink.
CLASSIFICATION & LABELLING
Collect leaking and spilled liquid in covered containers as far as possible. Then wash away with plenty of water.
According to UN GHS Criteria
Separated from oxidants. Well closed. Dry.
PHYSICAL & CHEMICAL INFORMATION
Physical State; Appearance
COLOURLESS VISCOUS HYGROSCOPIC LIQUID OR CRYSTALS WITH CHARACTERISTIC ODOUR.
The substance is a weak base. Reacts with oxidants. Decomposes on burning. This produces toxic and corrosive fumes including nitrogen oxides.

Molecular mass: 149.2
Boiling point: 335.4°C Melting point: 21.6°C Relative density (water = 1): 1.1 Solubility in water: miscible Vapour pressure, Pa at 25°C: <1 Relative vapour density (air = 1): 5.1 Relative density of the vapour/air-mixture at 20°C (air = 1): 1.0 Flash point: 179°C Auto-ignition temperature: 324°C Explosive limits, vol% in air: 3.6-7.2 Octanol/water partition coefficient as log Pow: -2.3 (not explosive)
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 irritating to the eyes, skin and respiratory tract.
Evaporation at 20°C is negligible; a harmful concentration of airborne particles can, however, be reached quickly when dispersed.
Effects of long-term or repeated exposure
Repeated or prolonged contact may cause skin sensitization.
OCCUPATIONAL EXPOSURE LIMITS
