3-CHLORO-1,2-PROPANEDIOL (RACEMIC MIXTURE)

ICSC: 1664

PHYSICAL & CHEMICAL INFORMATION
Physical State; Appearance COLOURLESS-TO-PALE-YELLOW HYGROSCOPIC LIQUID. Physical dangers No data. Chemical dangers Decomposes on heating and on burning. This produces toxic fumes including hydrogen chloride (see ICSC 0163). Reacts with strong oxidants. This generates fire and explosion hazard.	Formula: C₃H₇ClO₂ / HOCH₂CHOHCH₂Cl Molecular mass: 110.5 Decomposes at 213°C Boiling point at 1.9kPa: 114-120°C Melting point: -40°C Relative density (water = 1): 1.32 Solubility in water: miscible Vapour pressure, Pa at 20°C: 27 Relative vapour density (air = 1): 3.8 Relative density of the vapour/air-mixture at 20°C (air = 1): 1.00 Flash point: 113°C c.c. Octanol/water partition coefficient as log Pow: -0.53 (estimated) Viscosity: 182 mm²/s at 20°C

EXPOSURE & HEALTH EFFECTS
Routes of exposure The substance can be absorbed into the body by inhalation, through the skin and by ingestion. Effects of short-term exposure The substance is irritating to the eyes and respiratory tract. The substance may cause effects on the central nervous system.	Inhalation risk A harmful contamination of the air can be reached very quickly on evaporation of this substance at 20°C. Effects of long-term or repeated exposure The substance may have effects on the kidneys. This may result in kidney impairment. Tumours have been detected in experimental animals but may not be relevant to humans. Animal tests show that this substance possibly causes toxicity to human reproduction or development.
