Methoxyethane

Methoxyethane, also known as ethyl methyl ether, is a colorless gaseous ether with the formula CH3OCH2CH3. Unlike the related dimethyl ether and diethyl ether, which are widely used and studied, this mixed alkyl ether has no current applications. It is a structural isomer of isopropyl alcohol. Its utility as an anesthetic and solvent have been investigated.
