## Synthesis

The usual method of synthesis is to take brominated neopentyl glycol and react with epichlorohydrin using Lewis acid catalysis to form the halohydrin. This species is then reacted with sodium hydroxide to form the diglycidyl ether.[1]

## Uses

A key use of the material is reducing the viscosity of epoxy resins. As an epoxy modifier it is classed as a reactive diluent, which may then be formulated into CASE applications (coatings, adhesives, sealants, and elastomers and composite materials).[2] As it is an organobromine compound it is used to improve the Flame retardant properties of materials.[3] Flame retardant coatings[4] including powder coatings maybe produced.[5]

## Toxicity

There is a trend to try and formulate away from brominated species in general because of the toxicity of the smoke produced when heated.[6]
