In organic chemistry, ethylenedioxy is a functional group with the structural formula R-O-CH2-CH2-O-R'. It is often attached to an aromatic ring.
Examples:
- 3,4-Ethylenedioxythiophene, a precursor to conductive polymer
- EDMA, an illicit analogue of methamphetamine.
- (ethylenedioxy)dimethanol, a biocidal formaldehyde releaser.
