| Hazard Information | Back Directory | [General Description]
A liquid. Flash point 85°F. Density about 9.7 lb/gal and practically insoluble in water (2 parts/100 parts water). Hence sinks in water. Vapors are heavier than air. Irritates the eyes but not to the skin. Releases hydrogen chloride, hydrogen cyanide, and hydrogen bromide gases when heated or involved in a fire. | [Reactivity Profile]
CHLOROBUTYRONITRILE(628-20-6) may attack some forms of plastics [USCG, 1999]. | [Air & Water Reactions]
Highly flammable. Practically insoluble in water. | [Health Hazard]
Chemical is moderately toxic. Inhalation causes irritation of nose and throat. Ingestion causes irritation of mouth and stomach. Contact with eyes causes irritation. Can penetrate the skin on prolonged contact; only slightly irritating. | [Fire Hazard]
Special Hazards of Combustion Products: Toxic and irritating hydrogen cyanide, hydrogen bromide, and hydrogen chloride may form in fires. | [Chemical Properties]
Clear Colourless Liquid | [Uses]
4-Chlorobutyronitrile (cas# 628-20-6) is a compound useful in organic synthesis. | [Production Methods]
4-Chlorobutyronitrile is readily obtained by reacting 1-bromo-3-chloropropane with sodium cyanide. It is used in the synthesis of the pharmaceuticals buflomedil and buspirone. 4-Chlorobutyronitrile also yields cyclopropanecarbonitrile upon cyclization with base. |
