[5] It is one of a number of glycidyl ethers available commercially that are used to reduce the viscosity of epoxy resins.

[10] Resorcinol and epichlorohydrin are reacted in the presence of a base and not a Lewis acid catalyst as normal with glycidyl ethers.

[13] The waste products are water and sodium chloride and excess caustic soda.

The material has two oxirane groups and is thus used mainly in epoxy resins systems as a reactive diluent and modifier.

[20][21] It is classed as IARC group 2B by the International Agency for Research on Cancer.
