CAUTION: Exposure by any route should be avoided. Somewhat less hazardous than acrylonitrile because of lower vapor pressure. Readily penetrates skin to produce systemic cyanide poisoning, death.
Use: In pharmaceutical and polymer synthesis. Combines the reactivity of a nitrile and an alkyl halide. Because of the cyano group the chlorine atom is more reactive than in ordinary alkyl halides.
