What is Epifluorohydrin?

Chemical properties

clear colourless liquid

The Uses of Epifluorohydrin

Epifluorohydrin is used as a reagent in the synthesis of N-arylphosphoramidates. In addition, it is used in the synthesis of orally bioavailable ALK inhibitors in the treatment of tumors.

General Description

Clear colorless liquid.

Air & Water Reactions

Highly flammable. Water soluble.

Reactivity Profile

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.

Health Hazard

ACUTE/CHRONIC HAZARDS: Epifluorohydrin is a lacrimator. When heated to decomposition it emits toxic fumes.

Fire Hazard

Epifluorohydrin is flammable.
