PHYSICAL & CHEMICAL INFORMATION
Physical State; Appearance COLOURLESS LIQUID WITH CHARACTERISTIC ODOUR. Physical dangers Chemical dangers The substance is a strong reducing agent. It reacts violently with oxidants. Decomposes on heating. This produces irritating fumes.

EXPOSURE & HEALTH EFFECTS
Routes of exposure The substance can be absorbed into the body by inhalation of its vapour, through the skin and by ingestion. Effects of short-term exposure The substance is irritating to the eyes, skin and respiratory tract.	Inhalation risk A harmful contamination of the air will be reached on evaporation of this substance at 20°C; on spraying or dispersing, however, much faster. Effects of long-term or repeated exposure Animal tests show that this substance possibly causes toxicity to human reproduction or development.
