3,4-Epoxycyclohexylmethyl-3’,4’-epoxycyclohexane carboxylate (ECC), also known as ERL-4221 is a cycloaliphatic, diepoxy functional organic compound that is a useful building block in the production of semi-hard to hard cured epoxy resins that are suitable for use at high temperatures. It can be used as a casting resin, in reinforced plastics and solvent-free adhesive system for UV resistance and anti-radiation properties.

ERL-4221 is often used in plastic embedding kits for electron microscopy. Polysciences makes number of low viscosity embedding kits containing ERL-4221:
