| Physical Description |
1-chloro-2,3-epoxypropane appears as a clear colorless liquid with an irritating chloroform-like odor. Density 9.8 lb / gal. Flash point 87 °F. Polymerizable. If polymerization takes place inside a closed container, the container is subject to violent rupture. Irritates the skin and respiratory system. Toxic by ingestion. A confirmed carcinogen. Vapors heavier than air. Used to make plastics and as a solvent. |
