A halogenated epoxide. Epoxides are highly reactive. They polymerize in the presence of catalysts or when heated. These polymerization reactions can be violent. Compounds in this group react with acids, bases, and oxidizing and reducing agents. They react, possibly violently with water in the presence of acid and other catalysts. The chlorinated derivative has been shown to be incompatible with aniline, strong oxidizers, sulfuric acid, isopropylamine, zinc, aluminum, iron, etc. see epichlorohydrin.
