'''Dimethyl ether''' ('''DME'''; also known as '''methoxymethane''') is the [[organic compound]] with the formula CH<sub>3</sub>OCH<sub>3</sub>, 
(sometimes ambiguously simplified to C<sub>2</sub>H<sub>6</sub>O as it is an [[isomer]] of [[ethanol]]). The simplest [[ether]], it is a colorless gas that is a useful precursor to other organic compounds and an aerosol propellant that is currently being demonstrated for use in a variety of fuel applications.

Dimethyl ether was first synthesised by [[Jean-Baptiste Dumas]] and [[Eugene Péligot]] in 1835 by distillation of methanol and sulfuric acid.<ref>Ann. chim. phys., 1835, [2] 58, p. 19 </ref>
