Properties: Crystals from n-hexane + benzene, mp 75-76°. Practically insol in water (soly at 25° = 11 ppm). Slightly sol in hexane; readily sol in benzene, ethylene dichloride. Hydrolyzed by alkali with liberation of the terminal chlorine. Hydrolysis under acidic conditions gives 3-chloroacrylic acid. LD50 orally in rats: 600 mg/kg (Bailey, White).
Melting point: mp 75-76°
Toxicity data: LD50 orally in rats: 600 mg/kg (Bailey, White)
CAUTION: May cause skin irritation.
